That clematis is a perennial. It is marginal in your area as the summer heat is at the maximum of its heat zone tolerance. You can plant it in a pot but I suggest amending some soil with compost and planting it in the ground where the roots will stay cooler in summer. The ideal location is with the roots in a "forest floor environment" (shaded and mulched) and the tops in half to three quarter day (mostly morning) sunlight. It will grow on most any support that it can wind around. Don't prune it until next year if even then.
Thanks for the question. Please stop in again soon!
