When in bloom, the nasturium-bauhinia looks like a reddish-orange bougainvillea from a distance due to its habit and profuse flowers. A semi-deciduous tree native to southeastern Africa, it grows upright, but has drooping, spreading branches that flop to the ground or on to nearby plants.

The leaves are rounded and divided into two lobes like other Bauhinia. They are a light to medium green and shed during the cool or lightly frosty winter season. The five-petaled flowers bloom most heavily in spring, but recur sporadically through summer and early autumn. Each blossom is red-orange to salmon with five claw-like petals. Hummingbirds and butterflies visit these blooms; this only occasionally leads to seed pod production.

Grow nasturium-bauhinia in full to partial sun and fertile, well-drained soil. It is fairly drought tolerant once established. Plant in acid to neutral soils for best health. Alkaline soils can cause nutrient deficiencies and leaf yellowing. This tropical small tree is best grown in areas where summers are moist and winters cool and dry. It will be killed back to the roots by winter cold in USDA zone 8 but will rejuvenate each spring. These plants also maintain a more shrubby habit.
