Allium sphaerocephalon (DRUMSTICK)-FALL PLANTING
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.
Easily grown in rich, sandy to gritty, dry to medium moisture, well-drained loams in full sun. Plants form dense, slowly-spreading clumps over time. Plants perform best with consistent moisture during the growing season, but tolerate drought after flowering ends. Plant new bulbs 3-5" (3 times bulb width) deep and 4-6" apart in fall.
Care Plant 2 to 4 inches deep in fertile, well-drained soil in full sun in autumn.
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.
