Crocus can flower any time from late winter to early spring. They appear on the scene very quickly. One day there will be no sign of growth and the next day you may discover them in bloom!
How long do crocuses bloom for?
Flowers will appear the first fall after planting (generally in September or October) and last for about 3 weeks. The grass-like leaves may emerge soon after the flowers or wait until the following spring.
Do crocuses flower more than once?
Crocuses will multiply once established and create their own colonies. If you want to propagate your collection, dig up large clumps in autumn and split them into smaller ones, or clean off individual corms and pot up.
