RHS / Joanna Kossak Appearance
Cleomes can reach 1-1.5m, with pretty, palmate leaves and spiny stems. These are topped with large, airy flowerheads in shades of pink, white, purple or rose from mid-summer to autumn. The flowers’ spider-like appearance is created by their numerous, long, slender stamens.
Preferences
Cleomes thrive in full sun and well-drained, fertile soil. They like warm weather and tolerate drought once established. Regular deadheading will prolong flowering.
Dislikes
They will not survive frost and dislike cold, damp soils and shady conditions. Young plants are sensitive to transplant shock, so they’re best sown directly where you want them, or moved carefully when very small.
Did you know?
Cleome is in the same family as edible capers, is closely related to brassicas, and some species are grown as leafy vegetables in Africa.
