Description
This remarkable grass-like plant was brought onto the market in Asia under the name Eriocaulon sp. "Japan", however, in the hobby, several different Eriocaulon variants are known under that name. Its species identity is still unclear. It is certainly not native to Japan and resembles certain Eriocaulon species that occur in rocky beds of fast-flowing rivers in India. Its submerged leaves are flexible, dark green and smooth. They grow to a length of approx. 30-40 cm with a width of only 1.5 mm. The leaves are distichous, which means that they grow in two rows on the rhizome-quite uncommon for an Eriocaulon. The creeping, short, hard rhizome branches readily, forming a large, dense grass-like tuft with time. Sometimes, young leaves get stuck when sprouting and become wrinkled. They can be removed and are normally followed by straight leaves.
Interestingly, this Eriocaulon attaches itself to solid material such as rock or wood. Therefore it seems likely that it occurs naturally on rock or in gravel in flowing waters.
Occasionally inflorescences appear that remain shorter than the leaves. When they are able to grow out of shallow water, its flowerheads open, exposing many tiny greyish white flowers. When the heads remain submerged, they develop adventitious plantlets.
