Dichelostemma capitatum

Synonym(s) Brodiaea capitata; Dipterostemon capitatus
Common name blue dicks
Family asparagaceae
Life cycle perennial
Flowers purple-blue (spring)
Size 30"

California wildflower. Grassy foliage grows from corms, with clusters of purple-blue flowers on wiry stems in spring. Dormant in summer. Reports of its hardiness vary widely, and in any case the hardiness will depend on the source of the seed - so I don't know if they'll be happy in our garden. Time will tell...

We're re-establishing this plant this year (it used to grow in our garden, but slipped away)
