PLANT OVERVIEW

About Myriophyllum 'Red'

A feathery whorled milfoil that flushes red on top.

This red-form Myriophyllum carries delicate, feathery whorls that turn pink-red near the tips under high light and CO2. Its fine texture and warm color make an eye-catching background, though it needs good light and dosing to hold red.
