Onion Weed

Botanical name: Nothoscordum borbonicum

Common Names

Wild Onion, False Garlic, Honey Bells

This is an upright herb to 105cm high with an underground bulb with many bulblets.

Leaves grow from the base and are linear, long, strap-like, smooth, mid to dark green and glossy.

Long cylindrical flower stalks grow from the centre of the plant. Flowers are bell-like, fragrant, in a small cluster at the tip of each stalk. Each flower has 7-pointed white to faint pink petals with pale green to brown markings along midvein. Flowers in spring to summer.

Fruit is a capsule, going from green to brown when mature. Seed is black.

This plant spreads by bulb and seed. If the plant is disturbed the bulblets break off easily and remain in the soil.

To control this plant cut off the flowers before going to seed.
