I'm looking for recommendations on some new clematis. I have 2 metal home depot bought trellises in my garage that my roses out grew, so thought why not use them for some new clematis. They're about 2.5' wide and maybe 6' tall. They would be placed between the spaces of 3 hydrangea. (2 Endless summer, blue, and burning embers, dark pink). To the right of this is my large white inside corner trellis with a Don Juan climbing rose (red) and Etoile Violette clematis (purple). The front of the bed usually gets some petunias (pinks, purples, white.

Any thought?
