Edible Uses

Edible Parts: Root
Edible Uses:

Bulb. The cooked bulb has a sweet, anise-squash flavour. Pressure cook at 250°F or 120°C for nine hours. A larger bulb than other species in this genus but the flavour is considered poorer [1-2]. Considered pungent, slimy, and bitter tasting by some (summitpost.org). The bitter taste is due to saponins in the plant. Commonly confused with C. quamash where Native Americans would harvest the roots to eat raw as a vegetables, or boiled them to create a sweet, molasses-like treat.

Cultivation details

Hardy Perennial Bulb found in temperate to subtropical locations. Prefers moist, fertile soil in full sun to partial sunlight. Soil chalk, loam or sand which is acid, alkaline or neutral. It tolerates clay and dry soil. Soil moisture moist but well-drained. Unlike most bulbs, it prefers soil that has a bit more moisture but is intolerant of waterlogging. Deer- and rodent-resistant. Flowers spring to early summer. The plant is heat tolerant in zones 12 through 1. (Plant Hardiness Zones show how well plants withstand cold winter temperatures. Plant Heat Zones show when plants would start suffering from the heat. The Plant Heat Zone map is based on the number of "heat days" experienced in a given area where the temperature climbs to over 86 degrees F (30°C). At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 (no heat days) to 12 (210 or more heat days). For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1). For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a clumper with limited spread [1-2]. The root pattern is a bulb.
