Echinodorus 'Barthii' is an excellent choice for beginners and one of the more compact and slower growing sword plants allowing it to be planted in midground areas of the aquarium. The melon sword as it is more commonly known has been the source for many other sword plant hybrids and cultivars on the market today. This sword is best for larger aquariums as it can become 25-50 cm tall and the whole rosette 20-30 cm wide. Depending on lighting, colour will vary from dark green to a deep red.
