Platanthera dilatata var. leucostachys is a perennial herb that is native to California, and also found elsewhere in North America and beyond.
[goorchids.northamericanorchidcenter.org] Pollination, Description, Range: Pollination
The fragrant white flowers of this orchid may be visited day or night by skippers or the nectar-drinking owlet moth, Mesogona olivata. These moths do not hover while they feed from orchids, but must land on the flower like a bee or hoverfly. The different lengths and shapes of the nectar-secreting spur found in the three varieties of this orchid strongly suggests that different insects pollinate this orchid over its broad range.
Platanthera dilatata var. leucostachys has a slender white spur, much longer than the labellum and is restricted to the Pacific Northwest from British Columbia deep into California. (link added by Mary Ann Machi)
