Depending on how much sun you receive at that site, I would suggest morning
glories. Sweet peas may do well until the summer heat really kicks in.
Clematis or climbing roses (joseph's coat for example, or climbing peace) may
dow ell for you also.
Make sure you amend the soil with some compost (available at your local
nursery) ........
