PLANT OVERVIEW

About Myriophyllum Mattogrossense

A fast-growing stem plant with bright green, feathery leaves.

Myriophyllum Mattogrossense is the feathery bright green stem plant that looks like a miniature pine forest once it bushes out, with fine whorled leaves branching densely along tall stems. It's a fast grower under moderate to high light, happy to stretch toward the surface if left untrimmed, so regular pruning keeps it full instead of leggy and bare at the base. Great as a background centerpiece or a school of fish hideout, and it doubles as a solid nutrient uptake plant that helps keep algae in check. Cuttings root easily too, so one healthy stem can fill out a whole background cluster over time.
