Drumstick allium is a fall-planted bulb grown for its eye-catching flower heads.
In late June and July, the flower heads appear, each composed of many tiny, reddish-purple flowers on long, upright stalks. The flower heads are about the size and shape of an egg. The thin leaves are hardly noticeable.
Plant in groups of 10 or more amongst other perennial flowers for a striking effect.
Drumstick allium is an interesting flower in mid-summer. At the Xeriscape Garden, it has proven to be tolerant of dry conditions.
It has spread by seed at the Cottonwood Creek Garden, but has been easy to pull out where we don't want it. It grows successfully when planted amongst other perennial flowers.
Cut back to ground level after the seedhead and stalk turn brown in mid summer. Will spread by seed the flowers are allowed to mature.
