When to plant crocus bulbs?
- Plant spring crocus bulbs in early autumn
- Plant autumn crocus bulbs in late summer
For your springtime displays, plant crocus corms in early autumn - September is ideal. Many crocus are native to Turkey and therefore it’s no surprise that they like a sunny well drained spot. They naturalise well in grass soon forming colonies before your very eyes! This is a plant to use in quantity - bold drifts and clumps are what these corms need. They also look well in pots, particularly terracotta.
Sweetly scented saffron crocus are planted in August and September for blooms in October and November. They need a dry sunny spot and are a real aristocrat of the Crocus world. The source of saffron - the world's most expensive spice, said to have been used by Cleopatra in her bath water! The vibrant orange red stigmas at the centre of the purple flowers are harvested and dried to flavour rice and sauces. For more information read our How To Grow Saffron Crocus Guide
Also flowering later in the year and known as 'autumn crocus' are the corms actually called Colchicum. Plant in late summer for an impressive show that same year. These flower mostly in purple on bare stems with the leaves appearing later. They can be planted in small numbers to great effect, as they are more individually showy. 'Waterlily' is very popular with up to 8 flowers per bulb. You can even grow Crocus bulbs indoors on a saucer with no soil needed, just plant out after flowering has finished.
From springtime carpets to an autumn full of spice - Crocus are certainly corms to consider.
