Diagnostics:

Diagnostic:Cleome rutidosperma is a very common weed of lawns. The key is to watch out for its trifoliate leaves. Each leaflet is somewhat diamond-shaped with no stalk. The flowers are very small (about 15 mm across) with upward pointing purple petals and protruding stamens and pistils.


Interesting Facts:

The Purple Cleome is naturalised throughout the tropics (eFlora, 2008). While tasting bitter, the leaves are eaten as a vegetable (Jansen, 2004).

In Malaysia, planting of this weedy herb around crop-fields helps to divert pest caterpillars of the diamondback moth (Plutella xylostella) such that the eggs are laid on the Purple Cleome instead (Jansen, 2004).
