Allium sphaerocephalon Allium sphaerocephalon

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The drumstick allium has egg-shaped flowers in summer that start off green, then bloom and develop to pink and then clover red-purple. These plants are attractive in a bed or border, especially peeking up through other plants, such as roses, so that their nondescript foliage is hidden. Their vertical presence and eye-catching flower shape are valuable additions to the garden, and they naturalize freely.

The first true double-flowering Oriental lily, this plant has delicate pinkish white blooms that open in July and August. They are as stunning in the mixed border as they are in the vase. Each bloom has 18 beautiful petals, making it unique among Oriental lilies.
