Echinodorus osiris with its red colour quickly became popular. It originates from Brazil and becomes 25-50 cm tall with a 20-30 cm wide roset. A nutritious bottom promotes growth, and when there is a shortage of micronutrients new leaves turn pale, thus indicating that fertiliser may be necessary. It is generally an undemanding plant which is suitable for both soft and hard water. The red colour of the leaves grows stronger at higher light intensities. It used to be sold as Echinodorus rubra. It is not eaten by herbivorous fish.
