Hygrophila sp. 'Red' is an unknown species from southeastern Asia. Introduced to the U.S. market in approximately 2003, it has apparently faded from cultivation there. It is, however, obtainable through the Asian aquatic plant nursery Oriental Aquariums. It may actually be from the related genus Staurogyne, but no specimens are presently available for comparison

Hygrophila sp. 'Red' is a heavily-branching, creeping plant which is reddish to brownish in color and is inclined to produce long leaves. It is relatively undemanding, but a nutritious substrate and good lighting produce larger and faster growth. Nitrate and phosphate fertilization will produce a slight acceleration in growth and will help to prevent the formation of spot algae on this species' leaves. CO2 supplementation is unnecessary. Lower nutrient levels tend to produce the best coloration in this species. H. sp. 'Red' develops an impressive root system.

Propagation is easy with this species since it develops many side shoots that can be trimmed and replanted. New shoots will also develop on any stem fragments that are left in the substrate.

Hygrophila sp. 'Red' is primarily suited to the foregrounds of medium- to large-sized aquaria. It is one of the only foreground plants available that is not primarily green in color, and stands of this species form an impressive contrast with plants of a bright green or red color.
