Rotala rotundifolia ‘H’ra’ is a narrow-leaved stem plant with an overhanging or creeping growth habit. Its shape resembles Rotala sp. ‘Green’, but suitable conditions can produce a warm orange planting rather than a green group.
Encouraging low, orange growth
High light, appropriate fertilisation and added CO2 encourage the stems to creep and develop their orange colour. These conditions are central to the low-growing effect described for the plant. Without them, the exact shape and colour should not be assumed.
The plant can form a dense midground cushion or a distinctive orange foreground carpet. Choose the intended position with its spreading stems in mind rather than treating it only as a vertical background Rotala.
Growth and layout
The profile rates growth as high and gives a height range of 3–20 cm or more. That broad range reflects the difference between low, creeping growth and taller stems. Light and CO2 requirements are medium, with stronger conditions specifically recommended for the orange carpeting effect.
Leave room for the stems to extend and maintain access to the group. The appearance of the established planting depends on the growing conditions and the way the stems are managed.
Tissue-culture format
Rotala rotundifolia ‘H’ra’ comes from tissue culture in a closed Tropica 1-2-Grow! cup. Its final colour and height describe development in the aquarium, not the appearance of every portion at delivery.
