If large, take a look at French Cabaret Blush Hibiscus. The summer flowers are sterile and you won’t have to worry about pulling up seedlings. If you want a medium sized shrub, Blue Puffball Vitex and weigelas would be good choices. Roses combine well with perennials and bulbs and Campfire has beautiful flowers. If you have room in the garden with the gladiolas and lilies, check out the phlox. The flowers are so fragrant!
