Pinxterbloom azalea is a deciduous shrub 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 2-6 (less frequently to 10) tall. Clusters of soft pink to white to lavender, slightly fragrant, funnel-shaped flowers (to 1.5Ă® across), each with 5 long curved stamens, bloom in April immediately preceding the emergence of the foliage. Oblong to elliptic green leaves. Pinxter means Pentecost (seventh Sunday after Easter) in Dutch, in reference to the bloom time for this shrub. Synonymous with and formerly known as R. nudiflorum.

Best grown in acidic, humusy, organically rich, medium moisture, moisture-retentive but well-drained soils in part shade. Tolerates dryish, sandy or rocky soils. Prefers a sun dappled or high open shade. Tolerant of sun in cool summer climates, but leaves may scorch in hot afternoon sun in hot summer climates such as the St. Louis area. Good soil drainage is essential (doesnĂt like ìwet feetĂ®). Poor drainage inevitably leads to root rot, therefore raised beds/plantings should be considered in heavy clay soils such as those present in much of the St. Louis area. Shallow, fibrous root systems (do not cultivate around plants) will benefit greatly from a mulch (e.g., wood chips, bark or pine needles) to help retain moisture and stabilize soil temperatures. Acidify soils as needed. Clip off spent flower clusters immediately after bloom as practicable.
