Rotala rotundifolia ‘H’ra’, also called Rotala ‘Vietnam H’ra’, has rather narrow leaves and an overhanging or creeping growth. It is a variation of Rotala that has much resemblance to Rotala sp. ‘Green’. High light levels, good fertilization and added CO2 will induce almost exclusively creeping growth and a warm, rich orange coloration. This makes it possible to create a dense, orange mid-ground cushion or even an unusual, orange foreground carpet.
