Plant of the Month for March, 2018

 (AL-ee-um  kar-uh-taw-vee-EN-see)

General Information:

Allium karataviense ‘Ivory Queen’ is a very unusual onion. The leaves are very wide, grow close to the ground and cup a large head of white flowers. Even in flower, the plant is only about 8 inches tall. Common names include kara tau garlic and Turkistan onion.

The species has pink flowers while the cultivar ‘Ivory Queen’ is white.  This plant has been in horticulture for a very long time, and I suspect any white flowering form is now called Ivory Queen. After flowering, the leaves slowly wilt and by midsummer the plant goes under ground, to appear again in spring.

Pollinators love the flowers and seed is easily produced. These will fall underneath the parent plant and produce grass-like seedlings. If you weed what you think is grass you’ll never have baby plants. Seedlings of Ivory Queen seem to come true and do not revert to the pink wild variety. It should flower from seed  in three years.
