True aquatic plant — has no emersed form. Grass-like yellow-green leaf, becomes bronze-reddish under high light. Compact rosette-like growth (actually a stem plant with closely spaced internodes). Naturally shoots downward for dense bushes. Flowers underwater — seed pods can germinate. Popular myth: Blyxa japonica needs soft water — this is WRONG. Tolerant of wide GH/KH range.
