Green Foxtail (Myriophyllum pinnatum)
Green foxtail is a pretty, bushy looking plant that is a medium grower, and requires high light levels. There is a red form of this plant which can make a nice color contrast. The green foxtail is also known as cutleaf milfoil.
The fine leaves may collect debris. Cyanobacteria covering the leaves might be enough to kill the plant. It may also be necessary to clean the leaves. (Or good to keep algae eating shrimp in the tank to help keep the leaves clean.)
This plant can be planted in the substrate. If you want to propagate Green Foxtail, then you should take a cutting at the height you would like and then strip about an inch of the lower leaves and then plant it in the substrate.
