Calochortus uniflorus (1 Page of 5) The Calochortus uniflorus plant species is found in Southwestern N. America - Oregon to California. It is a member of the Calochortaceae family. Some home gardeners know the variety as C. lilacinus. Kell. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Calochortus uniflorus Family: Calochortaceae Author: Hook.&Arn. Known Hazards: None known Mature Height: 0.3 Mature Width: Habitat: Low meadows on the eastern side of the Cascades[60].
Cultivation Notes: Requires a deep very well-drained fertile sandy soil in a sunny position and must be kept dry over winter[1, 200].
This is a rather difficult plant to cultivate in Britain, it is very cold hardy but is intolerant of wetness especially in the winter[1]. Another report says that the plant requires plenty of moisture when in growth, but very dry conditions after it has flowered[245]. It is easiest to grow in a bulb frame but is worth trying outdoors at the base of a south-facing wall, especially with shrubs that like these conditions[120]. The plants should not be crowded by other plants[214]. Bulbs have succeeded in a cold frame with the cover removed from March to October[214]. Bulbs can be lifted as soon as the foliage dies down in the summer and stored overwinter in a cool dry place, replanting in spring[138]. Another report says that they should be replanted immediately[1].
Bulbs frequently divide after flowering, the bulblets taking 2 years to reach flowering size[200].
The flowers are sweetly scented[245].
Hand pollination is necessary if seed is required.
