Orchid Tree
The orchid tree (Bauhinia spp.) has orchid-like blooms that are 3 to 4 inches across and can be pink, purple, white, yellow and red. It can be deciduous, semi-evergreen or evergreen and may flower year-round. Orchid trees grow to 25 to 30 feet tall with a 25- to 30-foot spread. The crown, or top, of the tree is rounded and the tree has an overall vase shape. The fruit appears as a 6- to 12-inch brown pod that does not attract wildlife. This tree needs part sun to full sun and can be grown in clay, loam, sand, slightly alkaline, acidic or well-drained soils. It is drought-tolerant and moderately tolerant of salt in the air.
The wood of this tree tends to be weak and subject to breakage. It must be pruned for vehicle or pedestrian clearance in most applications. It is considered a high-maintenance tree.
The orchid tree is hardy in USDA Plant Hardiness zones 9B to 11.
