When selecting plants for a southern exposure, choose species that prefer full sun or sun to light shade. Southern exposures receive the most sunlight and experience the warmest temperatures. Shrubs for southern exposures should have some measure of drought tolerance, as full sun exposure is often associated with dry soils, according the Purdue University Cooperative Extension Service. Before planting, enrich the soil with organic matter, such as peat moss or compost.

This sun-loving shrub tolerates alkaline soils. Common lilac produces a profusion of showy, fragrant purple flowers in spring. Border forsythia (Forsythia x intermedia) grows up to 10 feet tall. This fast-growing shrub is pest- and disease-resistant. Border forsythia produces abundant yellow blooms in spring.
Small Deciduous Shrubs
The dwarf crepe myrtle (Lagerstroemia indica) grows up to 3 feet tall. Shrubs produce multi-colored blossoms in summer and orange, yellow and red fall foliage. This fast-growing shrub thrives in moist, well-drained soil. Japanese barberry (Berberis thunbergii) grows up to 5 feet tall. This thorny shrub produces an abundance of yellow flowers in spring and red berries in fall. This hardy shrub tolerates heat, drought and pruning.
