Camassia quamash

Camassia quamash or Camassia esculenta is a perennial plant that forms large and generous clumps. It grows quickly and can reach a height of 50 to 70cm (20 to 28in). Its flower spikes, measuring 20 to 30 cm (8 to 12in) long, produce star-shaped flowers that are 3 to 5 cm (1 to 2in) in diameter. These vibrant blue flowers bloom from May to June. The deciduous leaves are linear and lanceolate in shape, measuring 20 to 50 cm (8 to 20in) in length, and are green in colour.

Originating from North America, this Camassia returns more vigorous each year. It can be found in perennial borders, wild gardens, wet meadows, as well as near water features. It can also be planted as an edging in your gardens. It is a good flower for bouquets. It has bulbs that are not eaten by rodents, so they can be left in place.

Also known as the Common Camas, Camassia quamash has bulbs that were once eaten by Native American tribes or used to make flour. When roasted or boiled, it tastes similar to sweet potato. However, all other parts of the plant are toxic. The word 'Quamash' means 'sweet' in the Native American language.
