Southgate® Radiance™ Rhododendron
Rhododendron 'Tyler Morris'

USDA Plant Hardiness Zones: 6a-9b  Find Your Zone >

Note:  For our customers who live and garden north of USDA Plant Hardiness Zone 6a, where this Rhododendron is not 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.

Special Attributes

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 clusters of large ruffled bright purple blooms that appear in spring atop mounds of lustrous, evergreen, dark green foliage. 

Landscape & Garden Uses

Growing 4 to 5 feet tall and wide, the Southgtate Radiance Rhododendron is a perfect choice for groupings, mass plantings, low hedges or an accent 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. 

Spacing:  4' for solid hedges;  8' or more for space between plants

Cultural 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
