Begonia luxurians, also known as the tree begonia or palm leaf begonia, is an evergreen perennial flowering plant in the family Begoniaceae, known for its tall growth habit and large, drooping, palmate leaves sprouting from bright-red, erect stems. Each leaf is divided into many narrow leaflets, giving a "palm-like" appearance. Small white or yellow scented flowers appear atop the leaves in spring and summer. In favourable conditions, plants can reach 2.5 m (8.2 ft) in height. It is native to southeastern Brazil.
Despite its common names of palm-leaf or tree begonia, B. luxurians is neither a member of the palm family, Aracaceae, nor is it truly a tree.
Typically, this species does not tolerate temperatures below 10 °C (50 °F); however, if given adequate protection and in appropriate climates—such as Southern California or Florida—B. luxurians will likely persevere winters down to the upper 40s (4-10 °C) and low 50s (10-15 °C). In temperate climates, or more northerly or southerly extremes, it needs to be grown indoors or in a greenhouse, in indirect or dappled light, or partially shaded or bright shade conditions. Soils should be acidic to neutral, and should be amended prior to planting, with plenty of added inert materials for drainage, such as perlite or pumice, or even vermiculite, to prevent rot. However, the mixture still needs sufficient organic matter to retain moisture, without being sopping wet, such as coconut husks (coco coir), rice hulls, compost, coffee grounds or earthworm castings. In the summer months, potted plants may be placed outside in a sheltered position, away from high winds and scorching sun. B. luxurians may benefit from a yearly (or twice-yearly) application of a mild, slow-release granulated fertilizer, or a monthly to fortnightly half-strength dose of water-soluble feed. For both methods, 50% of the recommended dosage is safest as to avoid leaf-burn or salt toxicity.
It has gained the Royal Horticultural Society's Award of Garden Merit.
