Bonatea speciosa. I've had poor luck with many kinds of terrestrial orchids outdoors; they do fine in mild weather, but once the summer heat sets in, they slowly dwindle and die. This species, however, spent the entirety of the record hot summer of 2023 outdoors in bright shade. Granted, it didn't do very much besides persist during that period, but considering how many plants simply gave up the ghost, I'm still impressed. It has resumed growing and is now in full bloom. In its native habitat of southern Africa, its flowers are pollinated by hawk moths, and at night they emit a strong smell I would compare to freesia or fruity cereal, with an edge of cleaning product.

Any chance you could tell me something about this plant?
Found it while hiking in Vermont (in the wooded area around a pond)
Yes! That is a pink ladies slipper (Cypripedium acaule), one of our showiest orchids. In New England, we are just passing the height of their flowering period and they will begin to die back (their two basal leaves stick around for most of the summer though!).
You may have heard about the importance of fungal mutualisms for orchid species, and pink ladies slippers are no exception. These relationships are so crucial to orchids because (unlike most seed plants) their seeds essentially consist of the embryo and the seed coat and are only viable for a short period of time--no store of energy for those babies! This means the parent plant has to put very little energy into their production, but it also means that these embryos are very vulnerable. Mycorrhizal fungi can penetrate the seed cost without damaging the embryo and can provide nutrients for it, essentially nursing the orchid. This is a mutualism because later, once the orchid is grown, it provides a similar service to the fungi.
Pink ladies slippers rely on the presence of fungi in the genus Rhizoctonia for this vital part of their life cycle.
