Aaron's farm azalea experts can tell you which azaleas will grow best and are best adapted to flourish in your garden area. Azalea plants are evergreen plants, and these bushes will grow best in acidic soils and must be protected from direct sunlight which can kill them after an extended exposure. Planting azalea bushes under shady trees is best for abundant flowering, and even pine trees form excellent growing areas for azaleas or oak trees. Many thousands of azalea plant cultivars have been bred by experts and by hobby gardeners, and Formosa azaleas seem to be the most popular and spectacular flowering varieties in the spring.
