This plant displays long, very narrow leaves with rounded tips that are bright green in colour with reddish hues at the stem tip in ideal conditions. The interesting leaf shape and downward arching tips make Rotala “Nanjenshan” an excellent midground focal point when planted in large groups.
It is a moderately easy plant to grow, primarily requiring medium lighting and regular fertilisation. Soft water and CO2 injection will help Rotala “Nanjenshan” grow more easily.
Like the more difficult R. wallichii, Rotala sp. Nanjenshan grows far more easily in water that is soft and rich in carbon dioxide. Unimpeded light and lots of iron are important as well and contribute to a rich reddish color in the apex of the stem. Finally, a well-designed and steady fertilization routine is important; without one, stunting and blackening may result. It does have its needs, but isn't exceptionally hard to grow.
The growing tips of this plant naturally arch downward and therefore lend it well to aquascaping. A large grouping planted behind some Cryptocoryne or hardscape makes an effective focal point. To achieve a more compact appearance, give the stand a haircut and wait for the abundant side shoots to grow in.
