False garlic (Nothoscordum bivalve)
Discover False garlic (Nothoscordum bivalve), a low-maintenance bulb with early white blooms, ideal for naturalizing in dry, sunny spots.
Complete Plant Information
Overview
Nothoscordum bivalve, widely known as false garlic or crow poison, is a valuable bulbous perennial for regions needing reliable early spring interest with minimal input. This species offers delicate, star-like white flowers atop slender stalks, providing essential nectar for early emerging pollinators. Gardeners appreciate Nothoscordum bivalve for its resilience and ability to thrive where more delicate bulbs might struggle.
Native to warm temperate regions of North and South America, false garlic establishes itself easily in various open habitats, including savannas and prairies. It possesses low maintenance requirements once established, flourishing even in poor, rocky soils. The superficial resemblance to true garlic, giving rise to the common name false garlic, is purely visual, as it lacks the strong onion or garlic scent of the Allium genus.
The value of growing Nothoscordum bivalve lies in its toughness and early season color display. Reaching just over a foot tall, it naturalizes readily, creating drifts of white bloom from March through May. This dependable perennial is perfect for adding casual, naturalistic texture to the spring landscape.

How to Grow
The best time to establish Nothoscordum bivalve bulbs is usually autumn, allowing the plant to settle roots before winter dormancy. Plant bulbs in well-draining soil—sandy or rocky media is highly preferred over heavy clay. Ensure the planting location receives plenty of light, ranging from full sun to partial shade, to encourage robust flowering in the spring.
Care for established clumps of false garlic is remarkably simple. These plants are highly tolerant of drought once established and resent excessive moisture, particularly in summer. Avoid heavy fertilization; rich soil can cause the foliage to become leggy and less attractive. Watering should only be necessary during prolonged, severe dry spells.
These bulbs naturally spread easily from seed, which is why they are recommended for naturalizing. Allow seed heads to mature if you wish for the population to increase naturally within lawns or prairie areas. In late spring, once the foliage begins to fade after blooming, you can trim it back, though leaving it until it yellows naturally is also acceptable. This resilient perennial handles Zones 5 through 9 with ease, requiring little winter preparation.
Landscape Uses
The primary suggested use for Nothoscordum bivalve is to naturalize it throughout the landscape. This bulb excels when allowed to spread freely in areas where neat borders are unnecessary. Plant them in open fields, large expanses of turf, or prairie restoration projects where they can contribute early-season biodiversity.
When naturalizing, consider planting Nothoscordum bivalve in drifts among lower-growing native grasses before they fully emerge. They also look charming tucked into rock gardens, blending their delicate white blooms with the texture of stone. Because their foliage dies back relatively early, companion planting with later-blooming perennials that appreciate dry conditions, such as certain Sedums or ornamental grasses, will help cover the receding leaves.

Noteworthy Characteristics
Nothoscordum bivalve, commonly called false garlic or crow poison, is a bulbous, herbaceous perennial native to the southeastern and south-central United States, with a range extending into South America. Found in open woods, savannas, and prairies, mature clumps feature narrow leaves and solitary flowering scapes topped with umbels of small, white flowers having yellow tinged bases, which are vital for early insect pollinators. The genus name Nothoscordum references its superficial resemblance to true garlic (Allium), but crucially, false garlic lacks the distinct odor associated with that genus.

- Drought
- Dry Soil
- Shallow-Rocky Soil
Potential Problems
Nothoscordum bivalve is exceptionally robust and generally avoids major pest or disease issues, contributing to its status as a low-maintenance choice. Because it naturally prefers drier, grit-filled soils, the most common issue arises from overly rich fertility or persistent wet soil, which can lead to bulb rot. To prevent rot, ensure excellent drainage, especially if planting in mixed borders. No significant insect infestations or common fungal diseases trouble this species under typical temperate growing conditions.
Frequently Asked Questions

False garlic (Nothoscordum bivalve) is reliably cold hardy in USDA Zones 5 through 9.
How large does Nothoscordum bivalve grow?
This species typically reaches a height between 0.75 to 1.25 feet tall, spreading narrowly from 0.25 to 0.75 feet wide per clump.
When does False garlic bloom?
Nothoscordum bivalve blooms quite early, usually from March to May, displaying its white flowers with yellow tinged bases.
What sun exposure does False garlic need?
This plant performs best when given Full sun to part shade conditions throughout the growing season.
Conclusion
The false garlic, Nothoscordum bivalve, provides unrivaled simplicity and reliable early spring bloom for gardeners seeking tough, established perennials. Its tolerance for dry, rocky ground makes it an excellent choice for naturalizing or filling difficult, dry-sun spots in the garden. Check your USDA Zone compatibility before planning fall planting to ensure successful establishment of this resilient beauty.
Companion Planting
When selecting companions for Nothoscordum bivalve, focus on plants that require similar low-water conditions and thrive in full or partial sun. Because the foliage of false garlic may recede by early summer, pairing it with late-season bloomers prevents bare spots. Consider low-growing native salvias or drought-tolerant ornamental grasses like Blue Grama (Bouteloua gracilis) to provide textural contrast throughout the summer months.
This early bulb also works well in simulated dry meadows, accompanying other robust spring ephemerals that can handle similar soil profiles. Avoid aggressively spreading or overly dense groundcovers directly around the bulbs, as this can compete for resources or create overly moist conditions that threaten the bulb health of Nothoscordum bivalve.
Wildlife Benefits
The delicate spring bloom of Nothoscordum bivalve is a crucial early food source for many local insects. The small, white, upward-facing flowers offer readily accessible nectar and pollen when fewer other plants are producing. This makes false garlic an invaluable asset for kickstarting the activity of early-emerging bees and butterflies in the landscape.
Planting large drifts of Nothoscordum bivalve maximizes its ecological benefit by creating a significant early nectar source. Since the plant is low-maintenance and naturalizes easily, gardeners can dedicate more resources to other areas while still supporting local pollinator populations with this reliable native perennial.
