Nana is the smallest of the Anubias barteri species, reaching a height of 2-6 inches (5-15 cm) with thick leaves that grow up to 2 ½ inches (6 cm) long and a little over 1 inch (3 cm) across. Diagonal lines run from the center vein to the outer edge of the bright green oval leaves. The underside of the leaf is a lighter green than the top and the veins are clearly visible. Almost indestructible, individual leaves can last for years.
Occasionally this plant will flower; this may occur when it is either fully submerged or partially above the water line, such as in a paludarium. The flower looks like a creamy white spadix, similar to a calla lily. Like the leaves, the flowers will last a long time, often several months.
Like all Anubias species, Anubias barteri var. nana is an extremely hardy plant which makes it popular for aquarium use as well as in paludariums. The leaves are thick, dark green and quite tough, almost to the point of feeling like leather. This makes them ideal for aquariums with species of fish that are known to nibble on or uproot plants. Even active Cichlids and plant-loving Silver Dollars aren’t able to destroy this plant.
