Echinodorus harbich is a cultivated plant which means it was created by mixing two different plants together. The rounded leaves give it quite a soft appeal and grows to about 25cm underwater which makes it quite manageable and not too dominating.
There are no special requirements for this plant - provide it with Neutro T and Neutro CO2 fertilisers for the best effect and pop a couple of TerraTabs underneath it every few months as it's a heavy root feeder. It will flower on the surface given time and correct conditions.
Note - the picture is a guide only and what you receive may be smaller (or larger) than the picture as we are not the growers and therefore cannot control the size. If you need to know specifically what size the plant is that we have atm, drop us an email and we can let you know.
