Cryptocoryne willisii is a perennial plant with deep green linear to egg-shaped leaves. It is amphibious and only the terrestrial plants get to flower. Cryptocoryne willisii is a rathersmall plant and spreads to thick turfy tufts in theaquarium. It proves a fine decoration together with othermore high growing Cryptocorynes such as Cryptocoryne beckettii. When growing by themselves reduce the water level and plant it in corners where detritus andother organic wastes tend to pile up - it benefits from such good nourishment. In contrast to some delicate Cryptocorynespecies diseases are rather rare. For several years this plant has wrongly been described as C. nevillii. However, C. nevillii does exists but it is rare and not suitable for the aquarium. For more information visit The Crypts Pages. Author: Tropica
