Genus Overview: Azalea

Common Name: Azalea

The Azalea is among the showiest of all shrubs when in flower. Being evergreen to semi-evergreen it gives your garden a well finished appearance even in winter. The azalea is a member of the rhododendron family and requires basically the same care as the rhododendron. They begin blooming from mid-March to early May and are prized for their vibrant colors and fine textured foliage. Azaleas can be planted in full sun or partial shade; however, it is best not to plant them where temperatures get too hot. This versatile shrub can be used in many aspects of the landscape. All require slightly acid loamy soil with adequate drainage. When planting be sure to plant 1/2” above the ground level, amend the soil only when necessary and mulched to help retain water and insure their survival. Growth habit varies from 2’ to 8’ with equal spread depending on the variety.
