Corms should be planted about 8cm (3”) deep in any good fertile garden soil. The winter and spring-flowering species are well suited to the rock garden or the front of borders, and the later Dutch varieties for groups, edging borders or naturalising.

For the best results, plant 8-10cm (3-4”) deep, 5cm (2”) apart, and leave undisturbed. Croci are suitable for a pot or bowl culture, with the exception of large-flowered Yellow Crocus, and may also be grown in pebbles and water. It is important to remember that they must not be forced too hard, as too much heat or dryness in the atmosphere will lead to excess of leaf and no flower.
