This evergreen plant can also be used for bonsai as it has attractive glossy foliage and stunning yellow, orange flowers, which are very fragrant and attractive to butterflies and hummingbirds.

Rhododendron austrinum is best grown in USDA Zone 9-11, in an area of full sun exposure with regular water. It can also tolerate partial shade, but the blooming will be minimized for this condition. When grown in cooler regions, such as Northern climates, growing the Rhododendron austrinum in a protected area and in a pot is highly recommended. to increase its chances of survival, place the pot in a sunny area, such as a sheltered porch or a heated greenhouse, and water frequently.

When exiting dormancy, Rhododendron austrinum requires higher levels of water than usual. To prevent flower bud aborting in cooler climates, place a protective layer of mulch around the plant in the fall and refrain from pruning plants.
