Sort of an odd question here...

I had planned to plant a clematis in a climbing rose this year, but ended up not ordering my roses or buying my arbor. But, I already had ordered my clematis (Clair de Lune, iirc).

What would be the best way to temporarily support my clematis until I have my arbor & rose bush? (Quadra, if it makes a difference). I am planning on them for next year, tho I may be able to do at least the arbor sometime this summer. Right now, it is a little one from Bluestone, with a little bamboo stake as support.
