Flowers

The lovely member of the onion family produces a 5-inch ball -- or umbel -- of tiny, vivid purple flowers atop a bare 2-foot-tall stem. Protruding stamens give the umbel a a soft outline. Rosenback's allium makes a striking accent in the garden or as a cut flower. (Note: The stems release a strong onion-like scent when first cut.) Like most members of the onion family, this blub-forming plant is undemanding.

Notable Varieties
Allium jesdianum is a similar species sometimes sold as Rosenbach allium. It has 6-inch purple umbels on 18 to 24-inch stems.

Care
Alliums require little attention once established.

Planting
Plant bulbs in the fall about 4-inches deep in well-drained soil.
