Propagation

Cuttings; simply take a cutting from the mother plant and remove the bottom leaves. This can then be placed into the substrate taking care not to crush the stem. In a short time the cutting will produce roots and a new plant is formed. Ensure that the cuttings receive plenty of nutrients in the water to promote quicker root growth.

Difficulty

Easy

Short Description

This is an excellent plant for beginners to live aquarium plants. It will grow very fast if a CO₂ system is used and there are plenty of nutrients in the substrate. If it is lacking in the nutrients the first signs are leaves falling from the bottom of the stems. These do best when planted in groups at the rear of the tank, if an open topped tank is used, the plant will grow above the water surface.
