Plant Pick: Fall Crocus

Latin name: Colchicum autumnale

by Vancouver Island Master Gardeners Association

An often forgotten bulb choice but one that delivers twice in a season, the Fall Crocus and its several varieties are both cheerful spring greenery and fall colouring in one bulb. Easily grown they naturalize without any fuss and brighten a gray dreary day in the fall.

Nothing like your early spring crocus, except perhaps similar in shape, the fall crocus bloom is large and eye catching. There are single petal and doubles in pink, white and purple goblet-shaped naked (as in leafless) six-petaled flowers that, if planted in groups, create a great display of fall colour.

In spring only the leaves show up with large wide swaths of bright green, sometimes ribbed, to offset and show off the other early spring bloomers in your garden. Planted about 10 cm deep these large bulbs are good naturalizers, easy to grow and propagate (just lift after blooming, split and replant) or save the seed and plant right away.

Be sure to plant them so the short flowers are able to be seen but the long leaves don’t hide early plants.
