Cyperus x bartii

Echinodorus x bartii (family Alismataceae). This species has very dark red new leaves that change colour to dark green as they get older. Echinodorus x bartii does not tolerate low temperatures well and in the winter the plant does not flower at all and has a very low or flattened growth habit. This plant does not grow as fast as the other species but can do well in a well lit aquarium where it is not shaded by other species. Day length seems to affect the propagation of this species as it does not seem to produce as many flower stalks and so less plantlets.
