This unusual onion produces small bulbs at the end of the flowering stem and does not seem to set any seed. Once large enough, the small bulbs can be detached and planted. They will then grow to a new plant that will start producing more small bulbs in a year or two.

Culture

Plant in 5cm tubes of outdoor potting mix and place tubes in a bright area out of direct sunlight and water enough to moisten the mix. Keep moist but do not flood the mix. When the leaves start to grow gradually introduce to more sunlight.

When roots appear at the bottom of the container, it is time to re-pot up to the next sized container. For containerised culture, aim to eventually put into 20cm shallow container.

If planting in the ground, grow the plant in containers during the first Winter, then plant in the ground in the Spring when new leaves start to appear.

These onions may not produce bulblets in their first year.

Protect from slugs and snails. Mildew can be a problem if the Summer has been wet and humid. A copper spray can treat this but is not strictly necessary as the mildew only affects the leaves. Aphids can be controlled by washing them down with a mild detergent solution.
