Rhododendron periclymenoides (synonymous with R. nudiflorum) is the common Pinxterbloom Azalea found in the lower Appalachian Mountains, Piedmont and Coastal Plains from Massachusetts to north Georgia and Alabama. The white to pink flowers open in mid spring as the foliage is expanding, are they slightly fragrant. The blossoms measure approximately 1 to 1.5 inches across and the stamens are more than twice the length of the corolla tube.

Discovered by the Rev. John Banister and introduced to England in 1734, this species is often confused with R. canescens. In addition to differences in the natural range of the two species, R. periclymenoides can be distinguished by its flower tubes which are typically fuzzy or pubescent but do not have sticky glandular hairs on the back.
