There are a handful of plants that aren't commonly seen, and are surprisingly adaptable to gardens across most of the country. Camassia is one. Delivering 2-3 foot stems of starry blue-violet flowers with eye-catching gold stamen, these are excellent plants for hard to manage moist areas.

This gorgeous true blue BC native has starry lily-like flowers on slender stems in spring from a tuft of grass like foliage. This species was an important food crop of the First Nations cultures that lived in and around the southern coastal parts of our province. The consistency when cooked is like a gummy potato.

With intensely blue, starry flowers in dense spikes in a carefree package the camas is a useful addition to gardens. It will gently reseed itself given light shade to full sun and some spring moisture. Dormancy starts in June so it is a great candidate for mixing with other perennials. 18 in. tall.
