Dwarf rotala

About

Rotala (Rotala rotundifolia) is one of those stem plants that earns its place in almost any planted tank, and it is a genuinely good starting point for hobbyists just getting into aquatic gardening. In the wild it grows along the edges of rice paddies, streams, and marshy ground across a broad stretch of eastern and southeastern Asia, from the Chinese provinces of Fujian and Yunnan through to Kyushu in Japan. It also turns up as an introduced species in parts of Europe, including Hungary, which gives you some sense of how adaptable it is. Submerged growth looks quite different from what you might see on the plant label. The round leaves suggested by its species name are an emergent form, while underwater the foliage becomes narrow and lance-shaped. Coloration ranges from green to orange-pink to a fairly deep red depending on how much light the plant receives and how lean the nutrients are kept. Stems grow quickly and respond well to regular trimming, which encourages bushy, compact growth rather than a leggy column reaching for the surface. It is a forgiving choice for newer planted tank keepers, tolerates a range of conditions without drama, and looks best planted in groups toward the mid or background of the aquascape.
