The origins of this small Echinodorus are some what unknown but what does make this plant special is the size that it grows to. Most Echinodorus grow to a large size but not this one - grows only to about 15cm in height.  Not only that but it grows slowly too which means it needs little maintenance. It does prefer a nutritious substrate so make sure (as a minimum) you're using Neutro TerraTabs which help feed plants from the roots.
Originating from South America the Echinodorus grisebachii Tropica is a splendid looking aquatic plant. With hammered leaves and small tips, new leaves will appear 'black' when they sprout but will grow into their bright shade of green.
