New Zealand Pigmyweed - Crassula helmsii
This member of the stonecrop family has small white flowers with four petals. Readily recognisable when growing at the edges of water bodies by its fleshy leaves.
Around shallow pools, ponds and ditches. Can be submerged, emergent and terrestrial.
June to September.
Originally from Australia and New Zealand and now naturalised in Britain where it has become quite widespread.
Increasingly common and probably still increasing in Leicestershire and Rutland, becoming a pest species in several places. In the 1979 Flora survey of Leicestershire it was found in only 5 of the 617 tetrads.
