Gardeners' Notes:

Positive coriaceous On Jan 3, 2015, coriaceous from ROSLINDALE, MA wrote:

This is one of our many beautiful native deciduous azaleas. The flowers are fragrant, ranging from white to pink, and bloom here in late May, appearing with or just before the leaves. The stamens extend far beyond the corolla, which has sticky glands on the outside.

The size ranges from 3 to 6' and as wide, with a suckering habit, and so this species is hardly dwarf.

There are naturally occurring hybrids with R. periclymenoides and also with R. austrinum, respectively pink and yellow.

Its needs are like those of most azaleas: moist well-drained soil preferably high in organic matter, and full sun to light shade.
