Good thought, Kathy. I have a bed in the shade of an oak out by the driveway. Nothing else around it but gravel driveway and 'mow what grows' lawn so if the little orchids start wandering out of bounds I'll see them right away. I also think if I'm diligent about removing seed heads, that might prevent unwarranted spreading, too. I think they'd make a really nice low feature out there where nothing else does well.
