Description: There are several varieties of this very hardy plant that do well in most aquariums, some of these are very small, forming a turf only 2,5 cm high; others are giants over 80 cm tall. They make ideal background plants. Sagittaria subulata can be used in harder water and even in slightly brackish conditions. A grasslike plant with leaves only 5 mm wide. These are bright green, with acute or rounded tips. In shallow water, small floating elliptical or egg-shaped leaves are produced, followed by small white flowers. It is a fast-growing species, which displays productive multiplication through runners, which will form a dense, about 5-7 cm thick "carpet" within a few weeks. Intense lighting will enhance slightly reddish leaf apaxes. Sagittaria subulata grows best in medium-hard to hard water with a pH-value within the moderately acid to alkaline range.
