Canada

I just planted my thumbergia grandiflora (sky vine - blue) in the spring. It does not look like it is doing very well and I am unsure as to why. It is in full sun, watered regularily, has both a trellis and bracing for support, yet the leaves are starting to get crispy and the vines withering and dying. Should I move it to another area of the yard with partial sun? As well, silly question, but is this a perennial? I would love for it to come back next year,. but at the rate I'm going, I think it might be dead in a month! Help!
I live in Alberta, Canada. In the late spring, after it was planted, we were hit with a few nights of frost. I had covered the plant at nights with sheets, but perhaps it was touched by frost. I would think though that after a month, new growth should begin - but it seems to be at a stand still. The average temperatures for the past 3 weeks have been about 20 degrees celcius, and averaging 10-15 degrees at night.
Your assistance is greatly appreciated
