Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Calochortus clavatus Family: Calochortaceae Author: S.Wats. Known Hazards: None known Mature Height: 1 Mature Width: Habitat: Dry, often rocky slopes below 1200 metres[71], usually on serpentine soils[90].
Propagation Notes: Seed - sow as soon as ripe or early spring in a cold frame in a very sharply draining medium. Stratification may be helpful. Germination usually takes place within 1 - 6 months at 15°c[138]. Leave the seedlings undisturbed for their first two years growth[138], but give them an occasional liquid feed to ensure they do not become nutrient deficient. It is quite difficult to get the seedlings through their first period of dormancy since it is all too easy either to dry them out completely or keep them too moist when they will rot[214]. After their second year of growth, pot up the dormant bulbs in late summer and grow them on for at least another 2 years in the greenhouse before trying them outside. Seedlings take about 5 - 7 years to come into flower[214].
Division of the bulbs as soon as the foliage dies down. The bulbs can be planted straight out into their permanent positions but in areas with wet winters it might be best to store them overwinter and replant them in the spring.
Stem bulbils, harvested from the stems after flowering. They can be stored cool and dry then planted in pots in the cold frame in the spring.
