Description: This red-leaved stem plant can be found in many different leaf forms and shades of color. The top leaf surface may vary from olive-green to brown, while the underside is pink-red. A good source of iron will help to intensify the red color. The plant is easy to care for if given the right conditions, which include strong lighting and a good iron-rich substrate. In larger aquariums, plant Alternanthera reineckii in small, well spaced groups around the center of the aquarium. The red leaves make the plant a good contrasting and focal specimen.

Should the lower leaves begin to rot with an otherwise healthy stem tip, this will always be due to light deficiency. Only under conditions of sufficient light intensity will the leaf topside be a reddish green color. A fine-grained, nutrient-rich substrate is best for initial planting and root formation of the sensitive stem. The pH-value should be weak acid.
