Echinodorus horizontalis is a medium-sized sword plant originating from the Amazon depression in the north of South America. In contrast to many other Echinodorus species that grow in more or less sunny locations, Echinodorus horizontalis is most often found on shaded ground of marsh woods or temporarily flooded forests or the banks of rain forest rivulets. There it is subject to rapid changes of the water level. When flooded, it develops submersed leaves that have the same form as its emersed ones.
Echinodorus horizontalis is a rather demanding plant when cultivated emersed in an aquatic plant nursery, it is susceptible to fungal diseases and has a lesser reproduction rate than many other sword plants. However, when cultivated submersed in the aquarium this plant grows quite well and even forms flower stalks with adventitious plants. Thus the survival of this beautiful plant in aquaristics depends almost entirely on hobbyists.
As the species name suggests, the leaf blades of Echinodorus horizontalis grow more or less horizontally, be it emersed or submersed. They are longish-oval with a heart-shaped base and an acute tip. The lateral veins meet the longitudinal veins in an almost accurate right angle. The transparent patterns (pellucid leaf areas) within the leaves form a grid-like pattern in this species. The leaf stalk is smooth, its cross section is round. The leaves are of a light to medium green colour, new leaves are often of a light reddish-brown. They are relatively firm and rigid.
