Fast, soft, lacy green for the back of your tank.
Water Wisteria (Hygrophila difformis) is a fast-growing stem plant with deeply cut, lace-like leaves that reach about 20 inches. It fills an empty background quickly and soaks up nutrients as it grows.Fast stem plants are the first line of defense in a natural tank. Wisteria roots at every node, so it feeds from both the soil below and the water around it.
-
Plant the stems in the sand cap. Push each stem about one inch into the sand, not into the soil. Or float it, and it will root from its nodes.
-
Wait out the change. Farm-grown leaves are rounder and can yellow in the first 1–3 weeks as the new lacy underwater leaves grow in.
-
Top and replant. When stems reach the surface, cut the tops and replant them. The bases branch out.
-
Is it a fern? No. It's a flowering stem plant. For a lacy fern, see Water Sprite.
-
Why did the leaves change shape? It's switching from farm-grown to underwater leaves.
-
Can it float? Yes.
-
How tall does it get? About 20 inches.
