Kotschy's Crocus Overview

Crocus kotschyanus has long-tubed, pale lilac flowers with yellow markings around the throat and cream-white stamens. It appears in late autumn, followed in late winter, by its leaves. Outside, grow Crocus kotschyanus - or Kotschy's Crocus, as it's also known - in well-drained, poor to moderately fertile soil. Plant the large, flattened, irregular shaped corms with the pointed end up, at a depth of 10cm and only water once - when planting in late summer - as they will rot if kept in damp conditions. Indoors, plant under glass in a free-draining growing medium, feed monthly and water regularly in the growing season but keep dry during dormancy.

Common problems with Kotschy's 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 Kotschy's Crocus

    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.

    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.
