Appearance
Broad heart-shaped leaves on long stalks. Colour and size vary widely between the forms of this species — from plain green to bronze and reddish, and from a modest rosette to a large one.
Keeping
Easy and slow: dim to medium light, no carbon dioxide needed, a nutritious substrate. Like all crypts it dislikes being moved and reacts to sudden changes in water by dropping leaves, which then regrow from the rhizome.
Placement
The middle or back of the tank, alone or in a small group — the leaves of a settled plant take up room.
Propagation
By runners, and by dividing the rhizome of an old plant.
