Gardeners' Notes:


On Mar 7, 2007, berrygirl from Braselton, GA (Zone 8a) wrote:

12-18 inch delicate native plant. Pink or white flowers "nod" from the stem, turning lilac as they age. This member of the lily family was used to flavor food and treat croup, colic, colds, fevers, kidney stones, dropsy, respiratory disorders. An endangered plant now found primarily in protected nature preseves. Low maintenance.

Sow seed outdoors in late fall.

I found this sweet little allium on some land behind my house slated for destruction. I dug up about 7 bulbs, and they are growing wonderfully. They transplant well and multiply each year, even in my freezing zone 3 garden.

This is one of the most attractive of our native Alliums. Pure white to light pink flowers are suspended on two foot tall stalks in July and August.

Increases vegetatively, and can be divided in early spring.
