The shrubs must require little upkeep and survive the winters without protection. Abelia is a glossy evergreen with pinkish-white summer blooms that takes sun to partial shade. Plant height and width is approximately 5 feet. Althea, or rose of Sharon, belongs to the genus Hibiscus, produces beautiful summer blooms and matures to about 12 feet in height and 5 feet in width. This plant is deciduous and takes sun to partial shade, and I suggest using it as an accent along the fence line.
Golden dewdrop is easy to grow and does best in sun to partial shade.
The top may freeze in a severe winter, but the roots are hardy. This hardy plant takes sun to partial shade and produces red-orange tubular flowers from summer into fall. Mature height and width can be in the 12-foot range. Wax myrtle also can be pruned into a small tree. Old roses are an option for sunny spots.
