Description
The Southgate Rhododendrons were bred in southern Louisiana to thrive in the heat and humidity of Deep South, as well as other traditional Rhododendron areas. We’ve grown them since 2011 in our central Georgia gardens and they’ve outperformed all other rhododendron we’ve attempted to grow. In addition to their heat and humidity tolerance, the Southgates are also very disease resistant and insect tolerant.
Southgate Radiance Rhododendron produces abundant, large clusters of ruffled bright purple bflowers that appear in spring atop mounds of lustrous, evergreen, dark green foliage. Probably our favorite of the Southgate Series!
Landscape & Garden Uses
Growing 5 to 6 feet tall and wide, the Southgate Radiance Rhododendron is ideal for use as a specimen, in groupings or as a natural hedge in partially shaded landscape borders and woodland gardens. We wouldn’t usually recommend a Rhododendron for home foundation plantings but have no problem doing so with the super-hardy Southgates! They do especially well on fertile embankments, hillsides and slopes. Can also be grown in large pots, planters and other containers with a diameter of 18 inches or more. A fine addition to purple theme gardens, rhododendron gardens and woodland gardens.
Suggested Spacing: 4 to 5 feet apart for solid hedges; 10 feet or more apart for space between plants
Note: For our customers who live and garden north of USDA Plant Hardiness Zone 6a, where this Rhododendron variety is not reliably winter hardy outdoors, you can enjoy growing it in containers that can be moved indoors during winter and placed back outside when temperatures warm up in spring.
Growing Preferences
When it comes to success growing Rhododendrons, a little good advice goes a long way. When planted right and in the right spot, Rhododendrons are very easy to grow and care for.
Rhododendrons thrive in a moist but well-drained acidic soil that is rich in organic matter and part shade; preferable morning sun with afternoon shade or heavily filtered sun. All day dappled shade is fine as well. Keep in mind that whether growing in the ground or in containers, constantly soggy or wet soil is problematic for Rhododnedrons, and most other plants for that matter. Some soils, such as heavy clay, quick-draining sand, or otherwise poor soils, might need to be amended to provide sufficient nutrients, better soil drainage, and/or moisture retention. In containers, select a pot with a drainage hole(s) and use a 50/50 blend of professional potting mix and potting soil. Avoid using any native soil in pots. Feed Rhododendrons after they bloom with an acid-loving formula such as an Azalea, Camellia & Rhododendron Food.

We bought one of these rhododendrons at a local botanical garden sale about 10 years ago. It is one of the few rhododendrons that is suitable for our Houston climate. It has thrived and we have been searching for another one for some time. So glad to finally obtain another one for our yard! It arrived in great shape and already in bud. Very happy with our purchase and would highly recommend both the plant and Wilson Brothers!———————————————-We are so glad you are pleased and we hope you enjoy it for years to come! Thanks for the kind words and great review! 🙂 Beth Steele | WBG
The plant arrived healthy alive and well. It’s arrived as promised and actually earlier than expected. We gave it a drink after unpacking as directed. It was package very well. We planted it the next day. It’s doing very well.

Equally big, healthy, and husky, well packed. I really got my money’s worth. The flowers were gorgeous, doing well in the yard so far.
