Hygrophila gracillima

A slender Hygrophila from seasonally flooded ground in northern Namibia and the DR Congo. It grows during the hot summer rains and faces a long, bone-dry winter. Almost nothing is published on it, so grow it like other wetland Hygrophila: warm, very bright and wet.

Where it grows wild

Probably grows on the muddy margins of seasonal pans, floodplains and rivers, as many Hygrophila do. The Namibian records fall in the Kavango and northern pan country.

No recorded elevation. The Namibian sites lie at roughly 1,000–1,100 m.
