Orchids survive in the strangest of places and sometimes the pampered greenhouse pet takes a shine to life in the great outdoors. A homecoming so to speak. One of the beautiful Laelia Cattleya crosses from tropical South America is such an orchid. Set free to grow on the log of a fallen tree on the banks of a creek in South East Queensland, it provides a glorious site. Seems quite at home among the gum trees and the Australian wildlife.
Probably infra dig according to some environmental enthusiasts, but in my books one little orchid is not going to do much harm. And the Kookaburras are laughing.
Who knows. Maybe way out there un the jungles of the Amazon some guy is planting an Aussie Dendrobium at this very moment.
