Swamp Azalea

Rhododendron viscosum

Swamp Azalea is a deciduous shrub that can grow 5 to 8 feet tall. It is particularly notable for its aromatic white flowers that appear after the leaves have fully emerged, emitting a pleasant clove-like scent. These flowers attract numerous pollinators, including butterflies and bees. Swamp Azalea has a bushy habit and prefers partial shade, flourishing in boggy or wet areas where other plants might struggle. Its adaptability to wet soils makes it an excellent choice for water-influenced landscapes, contributing both ecological and aesthetic value.

Maintenance Tips

  • Naturally suited to wet conditions; ensure consistent moisture, particularly in dryer environments.
  • Prune after flowering to maintain shape and promote more vigorous growth.
  • Best in acidic, moist, well-drained soil; amend with organic materials to enhance fertility.
  • Apply an organic mulch layer to maintain soil moisture and cool root temperatures.
  • Keep an eye out for pests like aphids and diseases such as powdery mildew. Proper spacing and airflow help mitigate these issues.
