spiranthes odorata for outdoors?

[catherinecarney]

Hi all--

I just bought a Spiranthes odorata from Andy's Orchids and am thinking about growing it outside in central Ohio. Here's the scoop on my growing conditions:
Zone 5
heavy clay soils (but I do have one spot that's been well amended with leaves and compost so it's a loamy clay and hosts Trillium sessile, T. grandiflorum, Wind ginger, jack in the pulpit, and native rue anemones)
Light is anything from shade to dappled shade to full sun depending on where I put it.

From what I've read, S. odorata likes moisture and a fairly high amount of sunlight. I gather is also needs drainage (moist but well drained soils). So, has anyone grown this in zone 5 or colder? What were the conditions? Anything in particular I should do??

My alternate plan since it's a temperate orchid is to pot it in a rich mix (cymbidium mix maybe?) and overwinter it in the garage where temps don't drop much below the 20's.

Thanks in advance!
