Here's some of the variation that earned these trees their specific name. At least in my experience, the variation is all within the pink to orchid color range. Oops! The net just corrected me. There are also white ones. In its native south Asia, where it's called kachnar, the buds are eaten stir fried, in dishes such as curries, and pickled. The curry sounds yummy. Being a curry, it almost wouldn't matter what the kachnar tastes like! Orchid tree is also popular with hummingbirds in the neo-tropics.
