These plants, resembling tufts of grass, live in swamps, and are therefore suited
to aquaterrariums, although they can also be cultivated in aquariums under strong
lighting, in hard, alkaline water.
When the stems of the spiked rush reach the surface, they spread out and do not
emerge above it. Vegetative multiplication occurs with the help of runners or the
division of a clump. Size: 20-30 cm.
