I’ve now found this species growing on two of our prairie areas. It’s growing in our largest mesic prairie remnant – the Knife Edge Prairie, and in a cleared savanna remnant on Indian Grass Point. It’s a small, delicate plant – smaller flowered, thinner stemmed and more delicate than Spiranthes magnicamporum. Wisconsin DNR considers it a plant of ‘special concern’. These records are the farthest north it’s been found in Wisconsin – the other records are in the southern two tiers of counties.
