Are Crocosmia Perennials

Plant crocosmia corms in spring for flowers in mid to late summer. In most climates, crocosmia is perennial and the plants will return to bloom again year after year.

Do crocosmia come back every year?

Crocosmia corms multiply each year and clumps can become congested, leading to reduced flowering and vigour. Established plants can be lifted and divided every 3 to 4 years. Carefully separate the corms and replant the top-most corms, which will produce vigorous plants for the coming season.

How does crocosmia spread?

How to propagate crocosmias. Crocosmia corms multiply over the years, forming new corms which grow on top of each other in a ‘conjoined string’. To propagate crocosmia, lift clumps in spring and gently pull the corms apart.
