Well they are growing as weeds. But I guess technically a weed means it is undesirable - which these are not. But I do have to pull 'em up from time to time when they start coming up in some places. These Nun's Orchids (Phaius tankervillia) come up almost everywhere - on tree trunks, on rocks, and logs. This time of year they all flower and make a nice statement throughout the forest.
