Garlic Chives | Plants

Allium tuberosum • Also known as: Chinese Chives, Oriental Garlic, Kow Choi

Existing data suggests potential roles in regenerative agriculture. One study explored its use in intercropping with sunflower on metal-contaminated soil, indicating that mycorrhizal inoculation can help reduce heavy metal uptake in garlic chives, suggesting a possible application in phytoremediation or for crops grown in challenging conditions. Continuous cropping of garlic chives, however, showed an increase in soil phosphorus and potassium over several years, without significantly impacting fungal or bacterial diversity. Another excerpt details the use of dried garlic chives as a component in a phytogenic blend for laying hens, improving feed intake and egg quality metrics. These findings point towards potential uses in polyculture systems, soil remediation, and as a component in animal feed within regenerative farming practices, though further research is needed to fully understand its broader regenerative benefits and integration into systems like rotational grazing or no-till agriculture. While coverage in our knowledge base is limited, the above represents documented uses in regenerative systems.

Regenerative Trait Ratings

How These Traits Are Calculated

Trait dimensions are ordered clockwise starting from the top of the chart (12 o'clock position):

1. Profit Potential

Net returns per acre from yield, pricing, input costs, and labor efficiency

WHAT: Synthesizes gross revenue potential, input costs, labor requirements, and storage/marketing advantages into net profitability per acre. Captures the complete economic picture from planting to sale.

WHY: Not all vegetables are equally profitable. High-value crops with efficient production can return $10,000-30,000/acre versus $2,000-5,000/acre for lower-value options. Profit potential guides crop selection for maximum return on limited land and determines viable scale for farm businesses.

HOW: Scored via LLM synthesis of economics data (yields, prices, costs), storage advantages (season extension, value-added potential), and labor intensity. Exceptional (3.0): High yields × premium prices with moderate inputs and good storage (garlic, high-value salad greens). Typical (2.0): Moderate returns (tomatoes, squash). Limited (1.0): Low yields, commodity pricing, or intensive labor requirements (low-value greens).

2. Production Reliability

Weighted: yield consistency (60%) + disease/pest resistance (40%)

WHAT: Combines yield reliability (harvest consistency year-to-year) with disease and pest resistance to measure predictable production. Reliable vegetables deliver consistent harvests without catastrophic failures from pests or weather.

WHY: Market commitments and CSA subscriptions require dependable production. Unreliable crops that fail in bad years or require intensive pest management create cash flow gaps and customer dissatisfaction. Reliable producers allow confident planning and reduce input costs from emergency pest interventions.

HOW: Weighted formula prioritizes yield reliability (60% weight) for overall consistency, with disease/pest resistance (40% weight) to prevent total failures. Exceptional (3.0): Consistent yields across variable seasons with strong natural pest resistance. Typical (2.0): Generally reliable with some pest/weather sensitivity. Limited (1.0): Highly variable yields or severe pest vulnerability requiring intensive management.

3. Climate Resilience

Temperature and rainfall tolerance across diverse growing conditions

WHAT: Measures the breadth of climatic conditions where the vegetable produces successfully—temperature extremes, humidity ranges, and rainfall variability. Climate-resilient crops work across diverse regions and weather patterns.

WHY: Climate variability is increasing—unexpected heat waves, cold snaps, or drought periods can wipe out entire vegetable harvests. Resilient crops provide insurance against weather uncertainty and allow geographic expansion for market growth. This is especially critical for direct-market farmers who can't easily substitute crops mid-season.

HOW: Ratings based on the climate_adaptability trait documenting temperature tolerance and geographic range. Exceptional (3.0): Grows successfully in diverse climates (cold to hot, humid to dry) with wide hardiness zone range. Typical (2.0): Moderate climate flexibility. Limited (1.0): Narrow climate requirements (tropical-only, cool-season-only, humidity-sensitive).

4. Growing Ease

Weighted: establishment ease (50%) + low maintenance requirements (50%)

WHAT: Combines establishment difficulty (germination, transplanting) with ongoing maintenance needs (watering, fertilizing, pest management) to measure total labor requirements. Easy crops grow reliably with minimal intervention.

WHY: Labor is the primary cost for small-scale vegetable production. Easy-care crops allow farmers to manage more production area with the same labor, improving profitability. Difficult crops requiring constant attention, precise timing, or specialized skills reduce overall farm productivity and increase risk.

HOW: Weighted formula balances establishment ease (50% weight) for reliable startup and inverted maintenance intensity (50% weight) for ongoing care. Exceptional (3.0): Direct-seeded or easy transplants with minimal water/fertility/pest needs. Typical (2.0): Moderate care requirements. Limited (1.0): Difficult establishment or intensive ongoing management (daily watering, heavy feeding, constant pest monitoring).

5. Space Productivity

Weighted: yield per square foot (60%) + season extension potential (40%)

WHAT: Combines spatial productivity (yield per square foot) with temporal productivity (extended harvest windows from succession planting or season extension). Maximizes production from limited growing area.

WHY: Land is the primary constraint for vegetable farmers—especially those near urban markets. Space-efficient crops delivering high yields in small areas improve per-acre profitability dramatically. Season extension (spring tunnels, fall protection) adds bonus production windows when competing supply is limited and prices are higher.

HOW: Weighted formula prioritizes space efficiency (60% weight) for core yield per area, with season extension potential (40% weight) for bonus production opportunities. Exceptional (3.0): High yields per square foot (10,000+ lbs/acre equivalents) with season extension options. Typical (2.0): Moderate yields and extension potential. Limited (1.0): Low yields or crops unsuitable for season extension.

6. Multi-Benefit Value

Ecosystem services beyond harvest—pollinator support, nitrogen fixing, pest habitat

WHAT: Measures ecosystem services provided beyond harvestable yield. Multi-benefit vegetables contribute to farm ecology through nitrogen fixation (legumes), pollinator support (flowering crops), beneficial insect habitat, soil building, or erosion control.

WHY: Cash crops can either extract from farm ecosystems or contribute to them. Vegetables with strong multi-benefit value build soil fertility, support pollinators needed for fruit/vine crops, and create habitat for pest predators—reducing external input needs. Nitrogen-fixing vegetables (beans, peas) provide $40-80/acre worth of fertility for following crops.

HOW: Ratings based on the multi_benefit_value trait documenting service contributions. Exceptional (3.0): Significant ecosystem services (nitrogen fixation, heavy pollinator support, soil building, pest habitat). Typical (2.0): Some ecosystem contributions. Limited (1.0): Single-purpose cash crops with minimal farm ecology benefits.

Ratings are based on documented performance in regenerative systems, not conventional high-input scenarios. All traits assume integrated management practices focused on soil health and ecosystem services.

Climate Suitability Assessment

Will this plant thrive in your climate?

IDEALLY SUITED

Köppen Zone: Cfa (Humid Subtropical), Cfb (Oceanic (Maritime Temperate)), Csb (Warm-Summer Mediterranean), Cwa (Monsoon-Influenced Humid Subtropical), Dfa (Hot-Summer Continental), Dfb (Warm-Summer Continental)
USDA Zone: 5a, 5b, 6a, 7a, 8a
Australian Zone: temperate
EU Climate Region: atlantic

Garlic chives perform optimally in regions with mild summers, consistent moderate rainfall, and cool to cold winters with snow cover, which are characteristic of Köppen Cfb, Dfb zones, USDA zones 5b-8b, Australian temperate zones, and EU Atlantic regions. These conditions provide a long enough growing season for robust vegetative growth and excellent perennial establishment. Temperatures typically range from 60-75°F (15-24°C) during the active growing season, with minimal risk of extreme heat stress. The cold winters, often below 0°F (-18°C) but buffered by snow, promote necessary dormancy, ensuring strong regrowth in spring. Establishment success is very high, often exceeding 90%, with minimal need for irrigation or specialized protection. Soil remediation functions are enhanced by consistent biomass production and root system development. Cash crop potential is high due to reliable, multi-year yields and ease of cultivation, fitting well into forage integration systems where consistent, palatable growth is valued.

ADEQUATE

Köppen Zone: Aw (Tropical Savanna), BSh (Hot Semi-Arid (Steppe)), BSk (Cold Semi-Arid (Steppe)), Csa (Hot-Summer Mediterranean), Cwb (Subtropical Highland), Dwa (Monsoon-Influenced Hot-Summer Continental)
USDA Zone: 4a, 9a, 10a
Australian Zone: subtropical
EU Climate Region: continental

Garlic chives are adequately suited to climates with distinct seasons, including Köppen Cfa, Csb, Dfa, Dwa zones, USDA zones 4b-5a and 9a-10b, Australian subtropical zones, and EU continental regions. These zones offer a sufficient growing season, but may present challenges such as hotter summers, drier periods, or colder winters that require some management. For instance, in warmer zones, summer heat above 85°F (29°C) can reduce vigor and increase disease susceptibility, necessitating supplemental watering or shade. In cooler zones, winter survival might be less reliable without mulch or snow cover, and spring growth could be slower. Establishment success is good (70-85%) with proper timing and site selection. While not as consistently productive as in ideal zones, garlic chives can still provide valuable soil remediation services, function as a secondary cash crop, and integrate into forage systems with moderate inputs and attention to seasonal variations.

NOT RECOMMENDED

Köppen Zone: Af (Tropical Rainforest), Am (Tropical Monsoon), ET (Tundra), BWh (Hot Desert), BWk (Cold Desert), Dfc (Subarctic)
USDA Zone: 2a, 3a, 3b, 11a, 12a

Garlic chives are not recommended for climates with extreme conditions that fall outside their optimal range, including Köppen BSh, Dwb zones, USDA zones 3a-4a, and specific challenging microclimates. These zones are characterized by very short growing seasons, extremely cold winters (below -20°F/-29°C), or prolonged periods of intense heat and drought. In cold zones, winter kill is almost certain, making perennial establishment impossible and limiting its use to a highly risky annual. In hot, dry zones, summer heat stress severely limits growth, reduces yield, and increases water requirements to impractical levels, often requiring intensive irrigation infrastructure. Establishment success rates can drop below 70% due to these harsh conditions. The plant's primary functions of soil remediation and reliable cash cropping are compromised, making it economically and practically unviable compared to more resilient alternatives. Significant effort and cost would be required for minimal return.

Better alternatives for these "not recommended" zones: Chives (Allium schoenoprasum) (More cold-hardy and adaptable to shorter growing seasons), Winter Rye (Extremely cold-hardy cover crop for soil remediation), Hardy Kale (Tolerates cold and can provide some biomass), Thyme (Drought-tolerant herb that thrives in hot, dry conditions)

Note: Zones listed above represent climates where this plant can produce reliably with reasonable management. Climate zones not mentioned would require intensive climate modification (greenhouses, extensive infrastructure) and are not economically viable for regenerative agriculture purposes.

Soil Suitability Assessment

Which soil types work best for this plant?

IDEALLY SUITED

Loam Soil

This plant thrives in these soil types without requiring amendments or remediation. Natural soil conditions support optimal growth and productivity.

ADEQUATE

Clay Soil, Rich Soil, Rocky Soil, Sandy Soil

This plant performs acceptably in these soil types with moderate, manageable remediation such as pH adjustment, compost addition, or drainage improvement. The required amendments are practical and cost-effective for regenerative agriculture.

NOT RECOMMENDED

Acidic Soil, Alkaline Soil, Desert Soil, Saline Soil, Wet Soil

Growing this plant in these soil types would require impractical remediation such as complete soil replacement, extensive amendments, or cost-prohibitive infrastructure. These conditions are not economically viable for regenerative agriculture.

Note: Soil suitability assessments focus on remediation requirements. "Ideally Suited" means the plant generally thrives without the need for substantial amendments, "Adequate" means manageable remediation (lime, compost, mulch), and "Not Recommended" means impractical soil changes would be required. Climate factors like rainfall and temperature also influence success.

Seasonal Considerations

Planting timing, growth duration, and harvest windows

Garlic chives are a resilient perennial that behaves as an annual for many growers, offering a continuous harvest. For seed starting, begin indoors approximately four to six weeks before your last expected frost. Transplant seedlings into the garden once the danger of frost has passed and soil temperatures consistently reach at least 50°F (10°C). Direct seeding is also effective, ideally done after the last frost when soil temperatures are similarly warm.

Garlic chives mature relatively quickly, with edible greens ready for harvest within 60 to 90 days of planting. The harvest window extends throughout the spring, summer, and into the fall, as plants are quite tolerant of both cooler and moderate heat. To ensure a steady supply, consider succession planting every four to six weeks through the early to mid-summer. Plants can withstand light frosts in the fall, allowing for harvests well before the ground freezes. They are also amenable to season extension techniques like row covers or cold frames, pushing the harvest period even further into cooler weather.

System Role & Multi-Benefit Value

Functional roles, integration strategies, and stacked benefits

Functional Role

Total System Value

Garlic chives offer a unique multi-benefit profile in regenerative systems, primarily centered on their soil remediation capabilities and direct harvest value. Their documented ability to absorb heavy metals like Cd, Cu, Cr, Zn, and Ni from contaminated soils (Excerpt 1) provides a direct ecosystem service, enhancing soil health and potentially making land arable again. Beyond this, garlic chives are a valuable culinary herb, contributing to direct harvest income and farm-to-table initiatives. While not a primary nitrogen fixer or large-scale windbreak, their dense root systems and foliage can contribute to soil structure improvement and erosion control in specific contexts. Their inclusion in diverse plantings can also support beneficial insect populations. By adding garlic chives, farms diversify their crop portfolio, reducing reliance on monocultures and increasing overall system resilience against market fluctuations and environmental stresses.

Integration Characteristics

Multi-Benefit Value: Adequate - Beyond their edible value, garlic chives enhance biodiversity by attracting beneficial insects and can be integrated into crop rotations to support overall system health.

Management & Care Requirements

Integration guidance, maintenance needs, and care practices

How to Integrate This Plant

Garlic chives, as a non-tree plant, can be integrated into regenerative systems primarily for soil remediation and as a culinary herb. Its ability to tolerate metal-contaminated soils (Excerpt 1) makes it a candidate for phytoremediation efforts in degraded areas. While not a primary nitrogen fixer or windbreak, its dense growth can offer some erosion control. Compatible practices could include intercropping within larger crop systems or as a component in polyculture beds. It can also be used in alley cropping systems, especially if managing for soil health in the alleys. The timeline to contribution is immediate for direct harvest and soil health benefits, with potential for increased soil microbial activity over time. Multi-benefit stacking includes direct harvest value, potential soil improvement in contaminated areas, and contribution to biodiversity through its presence in diverse plantings.

Integration Practices & Management

The provided knowledge base offers limited insight into the specific regenerative agriculture integration methods for Allium tuberosum. While one source () details intercropping garlic chives with sunflower in a pot experiment focused on metal remediation, it does not elaborate on establishment practices like seeding rate, timing, or tillage methods used by farmers. Similarly, there is no information regarding the integration of Allium tuberosum with grazing systems, including mob grazing, rotational patterns, or termination strategies such as natural winterkill, grazing, crimping, mowing, or herbicide application. Management considerations like fertility needs, competition control, and succession planning are also not addressed. The knowledge base does mention continuous cropping of Chinese chives for up to 5 years (), indicating it can be a monoculture crop, and a trial using Allium tuberosum powder in animal feed (), but these do not detail regenerative farming integration. Therefore, based on these sources, practical farmer experiences and detailed regenerative management strategies for this plant remain largely undocumented.

System Enhancement Value

Beyond harvest: soil healing, contamination removal, and land restoration

Soil Remediation & Building

Garlic chives (Allium tuberosum) offer significant system benefits primarily through soil remediation and pest management. As indicated in the knowledge base (), garlic chives, especially when intercropped with other plants and inoculated with arbuscular mycorrhizal (AM) fungi, can significantly reduce heavy metal (HM) concentrations in the soil by promoting rhizosphere competition and immobilizing these metals. This process not only cleanses contaminated soils from sites like WEEE-recycling areas but also enhances plant growth by alleviating HM toxicity. Furthermore, garlic chives are highly effective at attracting beneficial insects (). These include predatory wasps like the blue-winged wasp (Scolia dubia), which targets Japanese beetles, and the Pennsylvania leatherwing (Chauliognathus pensylvanicus), a predator of aphids. This natural pest control reduces the need for chemical interventions, contributing to a healthier farm ecosystem and potentially lowering input costs. Their potential to improve soil health and biodiversity makes them a valuable component in integrated farming systems focused on ecological resilience.

Ecosystem Service Contributions

Environmental contributions: carbon, pollinators, wildlife, and water

Carbon Sequestration: Garlic chives, being a perennial herb with potentially dense root systems, contribute to soil organic matter accumulation and thus carbon sequestration. The extent is variable and depends on management practices and soil conditions.
Pollinator Support: Medium: While not primarily a nectar-producing plant for broad pollinator attraction in the same way as some other flowering plants, garlic chives do attract beneficial predatory insects, which are crucial for integrated pest management. Their flowers can also be a food source for some smaller pollinators.
Wildlife Habitat: Low: Garlic chives do not typically provide significant mast, nesting, or browse for most wildlife. Their primary role in this regard is indirect through supporting beneficial insect populations.
Water Quality: Not applicable

Why farmers use this plant and additional resources

Why Regenerative Farmers Use This Plant

Garlic chives (Allium tuberosum) offer significant economic potential as a high-value specialty cash crop within regenerative agriculture systems, particularly for direct-to-consumer markets, CSAs, and specialty wholesale channels. Their perennial nature and vigorous growth habit contribute to consistent yields, with mature plants producing an abundance of flavorful leaves. They provide a compelling niche for regenerative farmers seeking high-value specialty cash crops with multiple market opportunities.

From a financial perspective, garlic chives can command premium prices due to their unique flavor profile and perceived health benefits. A well-managed patch can yield multiple harvests per season. Typical yields for mature stands can range from 5,000-10,000 lbs/acre (5,600-11,200 kg/ha), and often higher in intensive systems, providing a consistent income stream. The mild, garlicky flavor appeals to a broad consumer base. Their attractive white flowers in late summer can also be sold as edible garnishes, adding another revenue stream. This versatility allows garlic chives to be a cornerstone of diversified farm income, contributing significantly to overall farm profitability.

Beyond direct revenue, garlic chives integrate seamlessly into diversified farm systems by enhancing soil health and ecosystem services while offering ecological benefits. As a perennial herb, they establish deep root systems that help improve soil structure, enhance water infiltration, and scavenge nutrients from deeper soil profiles, reducing the reliance on external inputs and contributing to a more resilient farming ecosystem. Their presence can also deter certain soil-borne pests and attract beneficial insects, acting as a natural form of integrated pest management. When managed appropriately, their dense foliage can offer some weed suppression, especially in younger stages or when interplanted.

The quantitative ecosystem benefits of garlic chives are often overlooked but are crucial in a regenerative context. While not a primary pollinator attractant like some flowering crops, their late-season blooms provide a valuable nectar and pollen source for bees and other beneficial insects when many other food sources are scarce, supporting overall biodiversity. Their robust root systems contribute to soil organic matter accumulation over time, enhancing soil carbon sequestration and improving the soil's water-holding capacity. This improved soil structure leads to better water infiltration, reducing runoff and erosion, and creating a more stable environment for subsequent crops.

Garlic chives have demonstrated success in various regional farm systems. In the temperate climates of the Pacific Northwest, USA, they are grown in raised beds for consistent drainage and are popular in farmers' markets and restaurant supply chains. Yields in these intensive market garden systems can reach 3,000-5,000 lbs per acre (3,360-5,600 kg/ha) annually after establishment. In the UK, they are cultivated in smaller market gardens and often integrated into herb rotations, providing a continuous harvest for local food businesses. Australian growers in cooler regions, such as Tasmania, find them well-suited to their climate, often including them in mixed herb plantings for specialty food distributors. In the humid subtropical climates of the southeastern United States (USDA Zone 7-8), they can be planted in early spring and harvested throughout the warm season, benefiting from irrigation during drier spells. In the drier, semi-arid regions of Australia (Zones 2-3), establishing them with autumn rains and providing supplemental irrigation during summer is key to sustained production. In the cooler temperate zones of Canada (Zones 3-5), they are best planted in late spring after the risk of frost has passed, with early harvests in summer and continued production until the first hard freeze. In European market gardens, they are often grown in beds alongside other culinary herbs, benefiting from composted soil and regular harvesting to maintain productivity. In the Mediterranean climate of Southern Europe, they can be planted in early autumn, benefiting from mild winters and producing well into spring before summer heat reduces growth. In the humid continental climates of the US Midwest, they are best planted in spring after the last frost and can be harvested throughout the summer and fall. In tropical highlands, where temperatures are moderated, they can be grown year-round with careful water management. Their perennial nature makes them a valuable addition to perennial polyculture systems, such as fruit orchards or vineyards, where they can provide a continuous cash crop while contributing to the overall ecosystem resilience.

How to Integrate This Plant

Practical guidance for regenerative systems

Establishing garlic chives can be achieved through direct seeding or transplanting, offering flexibility in farm planning. For direct seeding, rates typically range from 1-2 lbs/acre (1.1-2.2 kg/ha) for broadcast sowing, or 0.5-1 lb/acre (0.55-1.1 kg/ha) for rows. A rate of 1-2 ounces per 1,000 square feet (28-56 grams per 93 square meters) is also typical. Planting depth should be shallow, around 0.25-0.5 inches (0.6-1.3 cm), as the seeds require light to germinate effectively. Spacing for direct-sown rows is generally 12-18 inches (30-45 cm) apart, with plants thinned to 4-6 inches (10-15 cm) within the row. For transplanting seedlings, which can be started indoors 4-6 weeks prior, plants are typically spaced 6-8 inches (15-20 cm) apart in the row, with 12-18 inches (30-45 cm) between rows, allowing for efficient growth and easy access for harvesting. Transplanting offers a quicker route to harvest.

The ideal planting window is early spring (March-April in the Northern Hemisphere, September-October in the Southern Hemisphere) or late summer for a fall harvest. In the Northern Hemisphere, sowing is best done in early spring (March-April) or late summer (August-September) to allow establishment before extreme heat or cold. Southern Hemisphere farmers should aim for September-October or March-April.

Management practices for garlic chives focus on promoting healthy growth and continuous harvesting while prioritizing biological fertility. They prefer well-drained soil and benefit from consistent moisture, ideally receiving about 0.5-1 inch (1.3-2.5 cm) of water per week, especially during dry periods. While they are not heavy feeders, incorporating compost or well-rotted manure into the soil prior to planting significantly boosts their vigor and yield. Fertility should prioritize biological approaches; incorporating well-rotted compost or aged manure at planting and annually thereafter is highly beneficial. Cover crop residue from preceding crops, such as clover or vetch, also provides excellent nutrients. Established plants are quite resilient and can produce for many years with minimal fertilization, often relying on the nutrient cycling from surrounding cover crops or compost applications.

Garlic chives typically reach harvestable size within 60-90 days from seed, and 30-45 days from transplant. Harvestable leaves can be taken within 60-90 days for young plants, and established plants can be cut back to about 2 inches (5 cm) above the soil line every 4-6 weeks for continuous harvest. Mature plants can reach a height of 12-18 inches (30-45 cm) for foliage, with the plant itself potentially reaching 1-2 feet (0.3-0.6 m). Regular harvesting of the leaves encourages more vigorous regrowth.

Within a regenerative production cycle, garlic chives excel as a perennial component in market garden systems or as an intercrop. They can be planted in permanent beds, allowing soil structure to develop over time. Succession planting is less about new sowings and more about managing harvest intervals to ensure a continuous supply. For instance, a farmer might divide established clumps every 3-4 years to rejuvenate growth and provide new planting material. Following a short-season annual crop, garlic chives can be planted in the fall to provide ground cover and begin building soil health for subsequent years.

For IPM, crop rotation intervals of 3-4 years with non-allium crops are advised to prevent the build-up of soil-borne diseases and pests. Their role in IPM includes deterring pests from neighboring crops; for example, planting them along the edges of brassica beds can help ward off flea beetles. Pest and disease management should focus on cultural practices like ensuring good air circulation, proper spacing, and timely harvesting to prevent fungal issues. Beneficial insects are naturally attracted to their flowers, aiding in pest control.

Post-harvest residue management involves chopping and dropping the foliage back onto the soil surface, where it decomposes to add organic matter and nutrients, or incorporating it into compost piles. Following the final harvest in late fall, it is beneficial to allow the plants to go dormant and then cover them with a light layer of compost or mulch for winter protection. To maintain soil health and break potential pest cycles, garlic chives should be rotated out of the same beds every 3-5 years, ideally following a nitrogen-fixing cover crop like crimson clover or hairy vetch, and preceding a heavy feeder or a root crop. In a cover crop rotation, garlic chives perform well following nitrogen-fixing cover crops like clover or vetch, which leave behind residual nitrogen. After the final harvest in the fall, planting a winter cover crop such as cereal rye or hairy vetch will protect the soil and further enhance soil organic matter.
