PLANT OVERVIEW

About Ammannia gracilis

A large stem with pink-orange twisting top leaves.

Ammannia gracilis grows tall with narrow leaves that curl and blush pink-orange near the top under strong light. It's an easier-than-it-looks red-toned background stem, tolerating harder water than many reds.
