Common Name
Dwarf Sweet Flag
Description
The Grass-leaf sweet flag or Japanese rush, Acorus gramineus, is widespread in East and Southeast Asia. It occurs i. a. at swiftly flowing, rocky forest streams and waterfalls, between pebbles, also clinging on rock by its roots. In these habitats, it is adapted to floods with strong current. Acorus gramineus is an old ornamental plant. There are several cultivars such as the white-striped 'Variegatus'. We offer the dwarf cultivar 'Pusillus' that mostly gets only about 10, at most 15 cm high. It is also named as a variety, Acorus gramineus var. pusillus. Otherwise, wild types of Acorus gramineus may get 30-50 cm tall.
The Japanese rush is often regarded as of limited value for aquariums. However, we found out that at least the Dwarf sweet flag, Acorus gramineus 'Pusillus', can be grown permanently submerged. Provided that the rhizome is not buried into the substrate, otherwise the plant may die off. It should be fastened to objects such as stone or wood where it attaches itself by its roots, or fixed to the ground, comparable to Anubias species or Java fern. The growth is very slow, and with time side branches on the rhizome may appear that can be cut off for propagation. Medium lighting is sufficient. Acorus gramineus 'Pusillus' prefers rather cooler temperatures; the optimum lies at 18-23℃. As a terrestrial plant, the Dwarf sweet flag is very easy to grow. The substrate, e.g. customary potting soil, needs to be moderately moist but not wet. The plant can overwinter cold, but frost-free.
