Outstanding Qualities

One of our great Northwest native bulbs, these tall, spiky, starry flowers have a lovely ice blue to sky blue bloom from late spring to early summer. This is one of the few bulbs that will happily naturalize in moist soils near ponds and streams, growing into large patches over time, getting better as the seasons pass.

Culture Notes
Camas grows best in full sun or light to open shade in rich well-drained to moist soils. It will tolerate a site that has standing water in the winter if the site dries in the summer. The bulbs multiply over time and can seed into the area to create impressive plantings. Plant the bulbs in fall or as potted plants in the spring. Old foliage can be cut back as soon as it starts yellowing in early summer.
