Didiplis diandra is a stem plant which can be found growing in lakes and streams throughout the states. Its a beautiful addition to an aquarium thanks to the thin, needle like leaves that can exhibit bright red tips when grown under high light with fertilization and CO2. In order to achieve the desired bushy effect, this plant is best  grown in groups or bunches.  

Propagation is simple and straightforward like other stem plants. Simply cut anywhere along the stem and replant the cuttings.  In order to keep this plant low growing and spread laterally runners, trim frequently and grow it under high light.
