The jewel-like tones of Crocus flowers are just one of the many reasons why these plants are loved by gardeners. Autumn crocus add a rainbow of colour to the garden as summer flowers start to fade, and Spring Crocus are one of the earliest plants to flower in late Winter. Since Autumn Crocus and Spring Crocus bloom during different seasons in the year, these corms need to be planted at their correct times.

Discover exactly when and how to plant Crocus corms and fill your garden with stunning Crocus flowers for most of the year.

What are Crocus corms?

Corms are very similar to bulbs, but corms are specialised sections of the stem. The appearance of corms differs from bulbs as corms tend to have a flattened shape.

When to Plant Autumn Crocus:

The best time to plant autumn-flowering Crocus is late July to September. Plant the corms around 4 inches deep in gritty, well-drained soil. These plants are perfect for pots and borders and will flower from September into November.

Tip – Plant Crocus corms in drifts in grassy areas or around other plants for a naturalistic look.
Here are some of our favourite Autumn Crocus varieties:

When to Plant Spring Crocus:

Spring Crocus bloom from late February into spring, so the best time to get these corms planted is September-November, just before the ground freezes in Winter. Plant Crocus corms around 4 inches deep in gritty, well-drained soil.
