RE: Red Bauhinia - a warm colour during winter.
Red bauhinia is a dense, semi-climbing, evergreen shrub with deeply-cleft, 2-lobed leaves that resemble the hooves of cattle (Fig. 1). The flowers of this sprawling plant are orchid-like in appearance, brick-red in color, and borne in few flowered racemes. The 1 1/2-inch-wide flowers of red bauhinia occur in the spring and summer and put on quite a show if the plant is trained on a trellis. The fruits are 5-inch-long pods that appear in the late summer, and these may be a litter problem.
Red bauhinia is nice in the landscape as an espalier, specimen, border, ground cover, and container plant. It climbs a fence nicely, producing most of the flowers near the top. It is a bit asymmetrical, perhaps even unkempt looking, making it best suited for the large-scale landscape planting.
Red bauhinia requires a location in the landscape in which it receives full sun and grows best on a well-drained, sandy loam soil. It often suffers from a deficiency of micronutrients in soil with a pH above 7. Preventive fertilizer applications help keep the foliage green. This plant requires little maintenance once it is established but may need early spring pruning or shaping for growth control.
