It blooms from late spring into early summer, bearing upright hyacinth-like spikes of starry blue flowers. Camas also produces narrow, straplike, deep green leaves that die back by late summer.
Plant camas bulbs in large drifts in early to midfall for a lovely display the following year. Smaller groups of camas can also be tucked in with moisture-loving shrubs and perennials for an ongoing show.
