The Story
Plant Bio
Rhododendron austrinum, commonly known as Florida azalea, is a deciduous multi-stemmed shrub native to wooded bluffs and stream banks of the southeastern United States. It forms an upright, loose branching structure reaching eight to fifteen feet tall with reddish-brown winter twigs and simple alternate foliage.
In early spring before the leaves fully emerge, dense terminal clusters of tubular funnel-shaped blossoms open in shades of yellow, peach, orange, or soft red with long protruding stamens. The fragrant blooms possess a contrasting darker central tube and produce abundant nectar that attracts early-season pollinators and hummingbirds.

Planting
How to Grow
- Choose a partial shade site protected from intense afternoon sunlight.
- Amend sandy or loamy soil with composted leaf mold or peat moss to lower pH below 5.5.
- Set the plant elevated slightly above the soil line to ensure rapid water drainage.
- Apply a 3-inch mulch layer of pine straw or shredded bark over the shallow root zone.
- Water regularly during the first growing season to maintain uniform moisture.
Pro Tip
Prune lightly immediately after spring flowering finishes; cutting late in summer removes next season's flower buds, while heading back into bare old wood prevents regrowth.

Common Questions
Florida Azalea questions
What zones can Florida Azalea grow in?
Florida Azalea is hardy in USDA Zones 7–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Florida Azalea deer resistant?
Not reliably. Deer may browse Florida Azalea, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Florida Azalea bloom?
Florida Azalea typically blooms in early spring through spring. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Florida Azalea need full sun?
Florida Azalea does best in part shade.
Is Florida Azalea drought tolerant?
Yes — once established (usually after the first full season), Florida Azalea handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
