Bauhinia galpinii (Red Orchid Bush)

Native to southern Africa, this sprawling shrub grows about 3 to 13 feet tall and can scramble more than 16 feet into surrounding vegetation. It is grown for its orange to brick-red flowers and can be trained against walls or fences. Each flower has three fertile stamens. Swallowtail butterflies transfer pollen on their fluttering wings, which touch the anthers and stigma while the butterflies feed on nectar. In Florida, United States, flowering extends from spring through fall. It is naturalized and an emerging environmental weed in southeastern Queensland, Australia, where it can form dense thickets. Photographed in Florida, United States.
