In western Africa, the Anubias Nana is a flowering plant found near river banks. In the wild, it is seldom seen growing completely buried in the environment; instead, it is more often found growing semi- or fully immersed on logs or large roots. For its thick, leather-like leaves, it's also known as "the plastic plant that grows."
In addition to being big, pointed and dark green, the leaves of this plant are arranged in low bunches. The leaf's central vein is clearly apparent, with diagonal lines going from the center to the leaf's periphery. How To Plant Anubias Nana
