Yellow Crocus Overview
Crocus flavus is a dwarf, deciduous perennial that grows from a corm. It has broad, linear-shaped leaves and goblet-shaped, scented, deep yellow flowers that appear in spring. Grow Crocus flavus in a sunny position, in well-drained, poor to moderately fertile soil. Whether on a sunny bank, in a border, container, coastal rock garden or a gravel garden, drifts of these Yellow Crocus will add winter cheer, wherever they are planted. They are also a vital food source for pollinating insects that are woken early by strong spring sunshine! Make sure you plant Crocus corms with the pointed end up at a depth of 8-10cm - in early Autumn. These low maintenance perennials will only need watering once - at planting time - and will rot if planted in damp locations.
Common problems with Yellow Crocus
Mice, squirrels and voles can dig up corms to eat and occasionally, birds will peck off the flowers. Stored corms are also prone to rots and mould.
How to propagate Yellow Crocus
Seed
Once ripe, sow into trays of compost three mm deep and place into a cold frame maintaining a temperature between 13C to 18C. Germination can take up to six weeks and the resulting seedlings should not be disturbed for two years. Flowers will appear in year three or four.
Division
Lift corms when dormant and separate the smaller cormels that have grown around the parent. Replanting these as soon as possible, at the same depth and orientation.
Budding
Bulbs
Bulbs or corms to a depth of 4 inches from the top of the corm and spaced 2-1/2 inches apart.
