These well-known, early spring flowers grow from corms. There are several different groups, including the Dutch crocus, the smaller Chrysanthus types, and the true autumn-flowering crocuses.

Suitable site and soil. Always choose a sunny position where the corms can be warm and dry in summer. The composition of the soil does not matter as long as it is very well drained and is not heavy clay. On wet, sticky soils, grow in raised beds.

Cultivation and care. Plant with about 2.5cm – 1 inch of soil above the top of the corm and leave them gradually to make clumps. Make sure that the leaves do not become damaged or 54 removed until seven weeks after the last flowers have faded, as they are needed to feed the corms.

Propagation Buy inexpensive corms. Plants raised from seed will flower after three years.

Recommended varieties. Large-flowered (Dutch) crocus flowers in early spring; ‘Queen of the Blues’ has very large soft blue flowers; ‘Snowstorm’ has large, globular, pure white flowers; ‘Remembrance’ is soft purple. C. chrysanthus crocuses flower a little earlier than the Dutch type. The many varieties include ‘Advance’ (yellow and bronze), ‘Snowbunting’ (white) and ‘Bluebird’ (white inside, blue outside). C. specio-sus varieties flower in the autumn.

Pests and diseases. Sparrows often attack yellow crocus flowers. Mice sometimes eat the corms.


The true autumn crocus,

Crocus speciosus , is not related to Colchicum autumnale, though this is also commonly known as autumn crocus. Both look similar and both grow from corms.
