ABC PLANTS - Rotala nanjenshan
Availability: | Out of stock |
Said to be a cross between Rotala rotundifolia and R. walichii, Rotala nanjenshan is in fact, a separate species that was recently discovered in ponds, lakes and other slow moving waterways in the scenic wilderness of Taiwan. It is similar in some ways to Rotala wallichii but is significantly easier to grow. Unlike R. wallichii, R. najenshan remains mostly a beautiful bright green color even in very intense lighting with only some redness developing on the tips.
It is an ideal plant that can be used to create dense midgrounds and backgrounds. It's leaves tend to be more delicate looking than Rotala rotundifolia but more robust and substantial than Rotala wallichii and is an extremely handsome plant for any aquascape and can create incredible dense patches when grown in good condition.
Unlike Rotala wallichii, R. nanjenshan does not require CO2 or extremely high light and can grow well in medium to high light without CO2, but does certainly benefit enormously from the amenities of a high tech tank.
