 a lot of trees and shading that then i there's not a lot of flowers that are going to bloom in the shade actually you know other than ground plantings like you know bleeding hearts and astilbes but i would say i would try a clematis the blossoms like sun but of course the by the roots like to be shaded so if you're going to plant a clematis you really want to plant annuals in the ground or you want to mulch it to keep the roots cool
