Summary
Rhododendron austrinum, commonly known as Florida Flame Azalea, is a deciduous shrub native to moist, acidic soils in pine flatwoods, hardwood forests, and along stream banks in the Southeastern United States. It typically grows up to 10 feet tall and 8 feet wide. This azalea is celebrated for its large, showy clusters of fragrant flowers that range in color from bright yellow to orange, often with shades of pink or gold, and bloom in early spring before the foliage emerges. The long stamens extend beyond the flower’s mouth, adding to its ornamental appeal.
Florida Flame Azalea is valued for its vibrant spring flowers, which are highly attractive to pollinators such as hummingbirds and butterflies. It is often used in residential landscapes, woodland gardens, and as a specimen plant. It requires acidic, well-drained soil and benefits from mulching to maintain soil moisture. While it prefers part shade, it can tolerate more sun in cooler climates. Regular watering is important, especially during dry periods. Potential problems include azalea lace bugs and root rot in poorly drained soils. It is relatively low-maintenance, provided it is planted in the right conditions.CC BY-SA 4.0
