The in vitro Rotala rotundifolia 'H'ra' brightens up any aquarium with its fine, elegant leaves that change from soft green to a vibrant orange under optimal lighting . This stem plant grows quickly and forms a charming little bush that perfectly adorns the bottom of the tank. Easy to maintain, it adapts equally well to conventional aquariums and demanding aquascapes. With regular maintenance and proper pruning, it offers a striking decorative effect. Its ability to change its color depending on the maintenance conditions makes it an ideal choice for bringing dynamism and originality to the aquatic environment.
Rotala rotundifolia 'H'ra' is a variety distinguished by its fine foliage and spectacular color. Halfway between the classic Rotala rotundifolia and Rotala 'Colorata', it retains a more delicate appearance, with slightly curved leaves and a creeping or semi-trailing habit depending on the conditions. Placed in a well-lit aquarium, it develops a vivid orange hue, perfect for contrasting with more traditional green plants.
Its rapid growth makes it an ideal plant for quickly filling an empty space in a planted container. It spreads into a dense bush that gives an impression of volume and movement. Although it can be used in the background, it is particularly appreciated in the middle of a container to structure a composition and add depth.
Although it adapts to many environments, this plant grows optimally under certain conditions:
It grows easily in a nutritious substrate , but can also adapt to conventional soil provided it has a good nutrient supply. A good filter is also recommended to prevent debris build-up and keep the water clean.
To fully enjoy the beauty of this plant, just follow a few simple steps. Remove the Rotala rotundifolia 'H'ra' from its in vitro dish, rinse it thoroughly to remove the growing gel, then divide it into several sections. Plant these sections in the substrate, spacing them slightly apart so they can grow well.
Its rapid growth requires regular pruning to prevent it from becoming overgrown. When pruned, it produces new side shoots, making the bush even more dense and colorful. To maximize its vibrancy, fertilization rich in iron and potassium is recommended.
Rotala rotundifolia 'H'ra' is highly valued by aquascapers for its bright appearance and ease of maintenance. It blends perfectly with green plants such as mosses, lawns or even decorative elements such as an aquarium root .
It can be used in a variety of ways: in the middle of a tank to structure a decor, in the background to create a dense plant mass, or even as a creeping carpet if it is cut very short and subjected to intense lighting. With its delicate foliage and evolving color, it adapts to all styles of aquariums.
