You might receive a better response on the Clematis forum.
I'm not sure what structure you have , perhaps a pergola or trellis?
How much coverage do you need? There are smaller flowered Clematis that are quite vigorous as the texensis hybrids which can tolerate heat well. 'Duchess of Albany', ' Princess Diana' 'Gravetye Beauty'are a few. Depending on the size of the area you want covered, perhaps you could plant more than one type of Clematis. |
