That seems to be the consensus, and I'm going with it.

I agree. They seem to be a pair, and to have been planted at the same time, probably recently since they have not flowered yet (maybe to help sell the house).
I think I should close this soon, and if I do get them through the winter in pots, re-open it with photos of blooms.
