Lophocolea semiteres

Identification notes

This non-native Lophocolea is definitely increasing in some areas and, where abundant, can out-compete native species. As with so many unwanted introductions, it is thought to have arrived through the horticultural trade and was first found in Britain in 1955. Unfortunately, it seems to be here to stay.

Typically robust, slightly aromatic plants forming large patches are readily recognisable as L. semiteres. Scattered, or smaller shoots may be indistinguishable from L. heterophylla unless the very striking male shoots are present (L. semiteres is dioicous).
