Rhododendron viscosum - Swamp Azalea
This deciduous azalea blooms in summer. The abundant white flowers have a spicy, clove-like fragrance that fills the garden. The flowers attract butterflies and hummingbirds. Plants grow into multi-stemmed shrubs that put on a show in fall with their flame-red foliage.
- Tough, winter-hardy azalea
- Flowers late so it extends landscape color
- Lustrous green foliage with great fall color
- Happy in poorly-drained soil and wetland areas
- White flowers attract butterflies and hummingbirds
Wooded and open swamps and along streams from Maine to Florida and west to Texas.
Rhododendron viscosum roots can be susceptible to root rot during extended flooding or in poorly draining soil, but they are hardier than other plants in the species and somewhat more tolerant of wet soils.
Grows well in acidic and humus-rich conditions in average to moist, well-drained soils. Avoid planting near black walnut and butternut trees.
