About this weed

Smooth Heliotrope is easily distinguished by its smooth, fleshy, grey-green leaves and small white flowers. There is some doubt as to whether it is a native or introduced. An interesting note about this weed is that material from this plant turns black on drying.


This small, prostrate annual or short-lived perennial grows to about 0.2 m high. It produces small white flowers between May and January.
