It is in flower from Jul to August. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, insects. Flowers numerous, tiny, star-shaped, in upright, tightly clustered flower head. Flowers are up to 10 mm across; tepals pink or purple with green midribs; anthers blue; pollen white or light gray. Often abundant populations of deep pink to white grow in spring-moist areas in steppe.
Allium douglasii produces egg-shaped bulbs up to 3 cm long. Scapes are round in cross-section, up to 40 cm tall..
Prefers a sunny position in a light well-drained dry to moist soil. The bulbs should be planted fairly deeply. Grows well with most plants, especially roses, carrots, beet and chamomile, but it inhibits the growth of legumes. This plant is a bad companion for alfalfa, each species negatively affecting the other. Members of this genus are rarely if ever troubled by browsing deer.
Seed – sow spring in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle – if you want to produce clumps more quickly then put three plants in each pot. Grow them on in the greenhouse for at least their first winter and plant them out into their permanent positions in spring once they are growing vigorously and are large enough. Division in spring. The plants divide successfully at any time in the growing season, pot up the divisions in a cold frame or greenhouse until they are growing well and then plant them out into their permanent positions.
