Pinxterbloom Azalea (Rhododendron periclymenoides)

Pinxterbloom azalea is a deciduous, woody shrub in the Ericaceae (blueberry) family that is native to moist woods, swamp margins, and open areas from Massachusetts to South Carolina and Tennessee. It is a dense, bushy, suckering shrub that typically grows 2 to 6 feet (less frequently to 10 feet) tall. The genus name derives from the Greek words rhodo, which means rose, and dendron, meaning tree.

This plant has a slow growth rate and prefers moist, well-drained, acidic soils in dappled shade with protection from afternoon sun which can scorch the leaves. It does not tolerate dense clay, so if you have clay soil, amend with organic material. Plant the root ball high in the soil to help with drainage issues. Avoid overwatering and over-fertilizing. Pruning, if desired, may be done after flowering. 

Pinxterbloom Azalea would be at home as an understory shrub planted in groups in woodland or naturalized areas. It can also be used as a hedge or as a specimen in a butterfly or pollinator garden where the flowers will attract hummingbirds and bees.
