Begonia melanobullata is a rare tropical plant originating from Northern Vietnam. This plant is characterized by its sideways stalked, droplet shaped leaves as with most begonia species. The base coloration of the leaves is light green. All over the leaves, in between the veins, a darker pattern of lumpy spots could be distinguished. The structure of the leaves is rutted. When the leaves are developing, they show a burgundy to red color. When mature, the plant produces a slender inflorescence with small yellow to green flowers, that are either male or female. Propagation is easiest by taking cutting of larger stems. When both sexes of flowers are present, it could be propagated by seed as well.

Begonia melanobullata grows naturally in shaded spots on tropical forest floors. This species requires constant temperatures of around 24 degrees Celsius. Do not let the temperature drop below 18 degrees. Humidity should be as high as possible; growing this species in a terraria or greenhouse is advised. Also allow for ample ventilation. Begonia melanobullata does not demand much light, artificial lighting or a shaded spot suffices. Place this plant in a humus rich soil that could retain water. It is important not to let the soil dry out completely, water this plant frequently but prevent the soil from becoming soggy. Fertilize this species with standard plant nutrients for green plants, 1/4 the recommended dose on a monthly basis.
