Propagation is very easy from seeds which are produced in abundance. Place drawstring bags over the seed heads, as it can be tricky to know when seeds will be dispersed. Sow the small, shiny black seeds in a well drained mix on the surface of 4" pots. Seedlings can take several years to mature into flowering size plants, so if you want a colony to develop quickly, dig up the plants in early Spring and divide the bulbs which can produce up to a dozen new plants in just a couple of years.
Wild hyacinth bears terminal racemes of blue flowers in late spring. The grass-like leaves are 1/2" wide at the base with an unbranched flower stalk. The bulb resembles that of a daylilly and can grow to 1" wide. Likes heavy clay, moist and well-drained soil.
Quamash was a major food source for Native Americans and was the cause of the Plateau Wars that led to the defeat of Chief Joseph and the Nez Perce in 1877.
Beware of a deadly species called Death Camas. They bear white flowers and were used by colonists to poison flies (hence the name Fly Poison).
