Unlike snowdrops, crocus come in a variety of colours. The large and later flowering Dutch forms are the best-known, often planted in drifts along verges or in public parks. Most are mixed colours but using a single colour can be very effective.
The smaller and slightly earlier hybrids of C. chrysanthus such as ‘Blue Pearl’, ‘Cream Beauty’, ‘Gypsy Girl’ and the white ‘Ard Schenk’ are all well worth growing. The small purple Tommy crocus, C. tommasinianus, will self-seed readily. C. sieberi ‘Tricolor’ is unusual but quite easy to grow.
Crocus have an advantage over daffodils when planted in grass as their foliage is less obvious as it dies down after flowering. It is essential to allow this to happen so that the corms will be strong enough to flower next year.
