Description and Ethnobotany
| Growth Form | Perennial herb with a grass-like growth habit. |
|---|---|
| Foliage | Leaves green or grayish-green, flat, linear and pointed (0.3 - 0.4 m long and 0.5 -1 cm wide). Leaves have parallel venation. Leaves tend to bend over rather than remain erect. |
| Flowers | Flowers white or creamy white, bisexual and star-shaped. Sepals look like petals. Flowers arranged in an inflorescence known as a rounded umbel (5 - 7 cm wide). Floral stalks grow to a height of 0.3 - 0.6 m. Flowers produce a fragrance similar to that of violets. |
| Fruit | Fruits are capsules, initially dark green and becoming beige and papery at maturity. Each capsule contains 3 black seeds. Seeds are ovate, rounded at the base and pointed at the tip (4 mm long, 3 mm wide at the base). |
| Habitat | In Illinois (USA), it was observed to naturalize in a meadow and along the edge of a ditch. In some areas in Europe and North America, it is considered an invasive weed. |
| Cultivation | Plant in well-drained, fertile, loamy soil (pH = 5 - 8). Individuals should be spaced 7 - 15 cm apart. To prevent excessive spread of the plant, remove the inflorescence before it sets seed. It will grow well in the same location without replanting for several years. It is resistant to pests and diseases. However, the plant is susceptible to fungal diseases when planted in waterlogged soils or dense populations. Propagate by seed or by dividing the rootball. Plants should be divided every 3 - 4 years due to its fast growth. |
| Etymology | The genus name “Allium” is Latin for garlic. The species epithet “tuberosum” is a reference to this species's thick rhizome. |
