Hygrophila auriculata
A spiny, upright marsh herb of the acanthus family, widespread in seasonally flooded ground across tropical Africa and South Asia. It grows fast in the monsoon, sets seed as the ground dries, and needs full sun and wet feet rather than greenhouse humidity.
Where it grows wild
Marshes, ditch edges, rice-field margins and seasonally flooded grassland, rooted in mud that is waterlogged in the rains and dries out afterwards.
Records run from sea level to about 2,470 m, with a median near 340 m; most are lowland.
