Siting for P. incarnata

I once had a P. caerula growing on the south side of my deck, on a slope. I don't actually water it there anymore, it's hard to get to. I grew a couple of incarnatas from seed, and was planning to put them there, I could try to remember to water. I could also put them on the south wall of my house but there is nothing to grow on. I can't think of places where they could be grown under a tree that have as good drainage, is that important?

Can they be planted out their first winter or do they need to be kept indoors over winter?

Will 2 seed-grown incarnates pollinate each other?

I was surprised when they sprouted, I had chilled them in the refrigerator and they weren't sprouting, so I kind of neglected to water them and suddenly they came up!

RE: Siting for P. incarnata

You can plant them in the yard now, in your zone. Protect them with mulch for the first winter. They WILL go dormant, but should return in the spring/May and grow like fury.

These vines will get massive and spread via underground runners, so make sure you want it - you will have it forever. Don't plant it near your house foundation - it will grow up through the siding and into the attic.
