Blyxa japonica is a true aquatic plant; one that does not have an emersed form and grows only under water. It originates from Asia, where it can be found in shallow ponds and rivers. Blyxa japonica has been in the aquarium hobby a long time, and is well liked for its bushy, grass-like growth form. It has yellowish green leaves that take on golden and reddish hues when grown under higher light levels. It is actually a stem plant, but the internodes are so closely spaced it looks like it is a rosette instead. The plant also favors spawning new shoots at the lower parts of the stem rather than top, which makes it naturally bushy. In favorable conditions, this plant will flower under water. The flowers develop into seed pods. These seed pods can lay dormant for a long time before sprouting new plants.

Blyxa japonica flowers open fully when they are able to penetrate the water surface.

Due to its medium height, Blyxa japonica does great in the mid ground of tanks. It can be used as a background plant in smaller tanks but it does require some time to gain height. Its controlled growth rate and height makes it great for aquascaping.

Blyxa japonica likes stability in its growth environment and takes awhile to adapt when transferred into a new tank/environment. During this transition period, shedding of leaves or even melting in severe cases is not uncommon. Once adapted to the environment and rooted, it is a very resilient plant that is tolerant of a wide range of growth parameters. However, it responds especially well to water column dosing - so for folks that want to grow their bunches of Blyxa japonica fast, having richer water column nutrient levels is the faster way to get speedier growth.

A popular myth is that Blyxa japonica is a soft water plant and needs soft water to grow well. It does very well in hard water - up to 10+ dKH/dGH. The problems that people face with it in hard water may well be tied to nutrient availability (the lack of) in harder water when dependent solely on water column fertilization. Using heavier water column dosing should side-step most of the issues when growing it in hard water.

While it can grow in non CO2 injected tanks; especially shallow ones with good gaseous exchange, it grows best with CO2 injection. Higher light levels give it an attractive golden/reddish color tone which gives a subtle tonal contrast to green plants. Moving a plant that was grown previously in the shade to a much brighter area tans the leaves quickly. However, sun tanning aside, it is not a particularly light demanding plant.
