Echinodorus 'Rosť' is a hybrid between E.
horizontalis and E. horemanii "Rot" and was first
produced by H. Barth in Dessau, the former Eastern Germany. On submerged plants the old leaves are
brownish-green whereas the young leaves are beautifully red coloured whereas
the emergent leaves are yellow-green. It is a very sturdy plant which does
not require any special conditions. It does, however, prefer a relatively
fertile substrate as most other fast growing plants. Many other new hybrid
aquarium plants are quite difficult to culture in the aquarium but Echinodorus
'Rosť' is very modest and at the same time beautiful too.
