Safety & Hazards

Camassia bulbs have long been an important food staple for native North Americans, especially in the Pacific Northwest of N. America, where the bulbs were dug and traded on large encampment meadows. However, the plants are superficially similar to the poisonous species of Zigadenus (known as ‘death camas’) and so great care should be taken in making a positive identification[1, PFAF].

Cultivation Details

HabitBulb
Growth—

A very easily grown plant, it succeeds in almost any soil[2] and is tolerant of considerable neglect once it is established[PFAF]. Prefers a moist, fertile, acidic, humus-rich soil in full sun, tolerating part shade[3, 4, 5]. Grows well in heavy clay soils. Prefers a rather heavy loam[6] that has plenty of moisture in spring but does not remain wet over the winter[3, 4]. Dislikes dry soils[4]. A very ornamental plant[6], there are many named varieties[4]. Plants often self-sow in the garden[PFAF]. Plants take 3 - 4 years to commence flowering from seed[5]. A good bee plant[7]. Plants can be naturalized in damp grass, this should not be trimmed until mid to late summer when the bulbs have flowered and the leaves have died down[8].. Plant the bulbs 7 - 10cm deep in early autumn and then leave undisturbed[6]. The bulbs should be planted about 10 - 20cm deep[9, 5].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[8]. The seed can also be sown in a cold frame in spring[8]. It usually germinates in 1 - 6 months at 15°c, but it can be erratic[3]. Sow the seed thinly so that it does not need to be thinned and allow the seedlings to grow on undisturbed for their first year. Give an occasional liquid feed to ensure that the plants do not become nutrient deficient. When the plants are dormant in late summer, pot up the small bulbs putting 2 - 3 bulbs in each pot. Grow them on for another one or two years in a cold frame before planting them out when dormant in late summer. Offsets in late summer. The bulb has to be scored in order to produce offsets.
