As long as they receive at least 4 hours of sun, clematis should work well for you. Hundreds of different ones to choose........you'll have trouble limiting yourself :-))

If it's a large lattice as well as wide go crazy !! But it's helpful to choose all the same type, so you don't have to worry about pruning . I mean , you can mix it up and do what you please of course ! :)

i love huldine , comptesse de Bouchard, Margaret hunt , prince Charles , mme Julia correvon and happy jack have been fantastic so far. These are all nicely vigorous.

Hop on over to bluestone perennials , they are having a sale on clematis. I was very pleased with mine this spring !
