Drumstick allium (Allium sphaerocephalon)
AL-ee-um sfay-roe-SEF-ah-lon
Genus:  Allium
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.
Noteworthy Characteristics:  The charming purple-red drumsticks bloom in midsummer and then fade as summer wears on.
Care:  Plant 2 to 4 inches deep in fertile, well-drained soil in full sun in autumn.
Propagation:  From seed, sow in containers in a cold frame when ripe or in spring. Some Allium take two years to germinate. Remove offsets in fall.
Problems:  Bulb rots in damp conditions. White rot, mildew, rust, smut, and various fungal leaf spots can occur. Onion fly and thrips are also possibilities.
