This plant growing in my courtyard turns out to be a Dwarf Red Orchid Tree (Bauhinia Galpinii). It is native to eastern and southern Africa. It seems to do well here in south Florida and, fortunately, does not have invasive qualities. It can eventually get to be 6 to 8 feet in height! Its main growth period is during the summer, but the blooms are fairly constant throughout. It is a relative of the more common Hong Kong Orchid Tree.
