Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Cultivation details

Prefers slightly acid soil conditions but succeeds in chalky soils if these contain plenty of humus[164]. Requires semi-shade, preferably provided by trees or shrubs, and a well-drained soil[42, 164]. Succeeds in almost any light soil, preferring one that is rich in humus[1]. Slugs love this plant and often eat out the leaves[90]. Flowers are produced in 3 - 4 years from seed[164]. Bulbs should be planted about 7cm deep[1]. According to some botanists, this species is no more than a variety of E. dens-canis[1].

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[164, 200]. Stored seed requires a period of cold stratification[164]. 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[1]. 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.
