Erythronium citrinum
Propagation: Seed - best sown as soon as it is ripe in a shady position in a cold frame. Water lightly in summer, it should germinate in autumn or winter[1][2]. Stored seed requires a period of cold stratification[1]. Sow as early in spring as possible in a cold frame. Sow the seed thinly so that it will not be necessary to prick them out for their first year of growth. Give an occasional liquid feed to the seedlings to make sure that they do not become nutrient deficient. When the plants are dormant, pot up the small bulbs putting 2 - 3 bulbs in each pot. Grow them on in a shady position in the greenhouse for another 2 3 years and then plant them out into their permanent positions when they are dormant in late summer.
Division of the bulbs in the summer as the leaves die down[3]. Larger bulbs can be replanted immediately into their permanent positions, but it is best to pot up smaller bulbs and grow them on in a shady position in a greenhouse for a year before planting them out when dormant in late summer.
Cultivation: Prefers slightly acid soil conditions but succeeds in chalky soils if these contain plenty of humus[1]. Requires semi-shade, preferably provided by trees or shrubs, and a well-drained soil[4][1]. Succeeds in almost any light soil, preferring one that is rich in humus[3].
Plants are hardy to at least -15°c[2].
Bulbs should be planted about 7cm deep[3].
This species is closely related to E. helenae, E. origonum, E. californicum and E. howellii[5].
Range: Western N. America - N.W. California, S.W. Oregon.
Habitat: Wooded and brushy slopes, 600 - 1000 metres[6].
Edibility: The following use has been noted for the closely related E. origonum and probably also applies to this species[K], which has a slender corm 4 - 7cm long and 15mm thick[6].
Bulb - raw, cooked or dried for later use[7].
Soil: Can grow in light and medium soils.
Drainage: Prefers well drained soil.
Seed Ripens: Early Summer-Mid Summer
Flower Type: Hermaphrodite
Known Hazards: Although no records of toxicity have been seen for this species, the following notes have been seen for another member of this genus and so some caution is advised.
Skin contact with the bulbs has been known to cause dermatitis in sensitive people[8].
