king begonia · Begonia rex
Also known as: fan plant; painted-leaf begonia
Painted-leaf begonia is prized for its vibrant foliage but is known to be a more challenging houseplant. Special care points include maintaining high humidity without wetting the leaves to prevent fungal diseases, and providing bright, indirect light to enhance leaf color without risking sunburn. Overwatering is a common issue, so ensuring well-draining soil and a potting mix that retains moisture without becoming soggy is crucial.
Painted-leaf begonia thrives in a humid environment, mimicking its native tropical rainforest habitat. It has a balanced water requirement, neither too dry nor too wet. The plant prefers watering every week to maintain optimal moisture levels. As an evergreen species, painted-leaf begonia can retain water well throughout the year, making it ideal for indoor growth where humidity control is possible.
