GG Gerbing Azaleas (Rhododendron 'Mrs. G.G. Gerbing') are vigorous, evergreen, Southern Indica shrubs known for producing massive, 3-inch, pure white blooms in mid-spring, with potential for fall reblooms. Growing 6–8 feet tall and wide, they are ideal for hedges, screens, or large foundation plantings, thriving in USDA zones 7–10 in sun-dappled orpart-shade conditions.
