Description
Relatively newly described, Spiranthes incurva (a hybrid S. cernua x S. magnicamporum) has white-ivory (with yellowish throats), fragrant flowers arranged in a spiral around the stems, like most species from the S. cernua complex. Long time ago it was easy to call all fall flowering Spiranthes, S. cernua but times have changed.
Those interested to read more about the S. cernua complex and see the differences between various species, the following article will keep you ‘entertained’:
As noted in the above article, there are morphological and geographical differentiations between S. incurve and its parents. Geographically speaking this species “entirely replaces S. cernua in the middle, northern, and eastern Interior Lowlands, Western and Northern Appalachian Mountains and Adirondacks, Great Lakes Basin, and Prairie Peninsula, from New Brunswick, southern Ontario, and southern Quebec, west to Minnesota, central Nebraska, and eastern Kansas”.
Germination: as usual for orchids; these seeds should be tried by someone with knowledge of ‘in vitro’ propagation.
