Helen Curtis Azalea

Helen Curtis Azalea (Rhododendron 'Helen Curtis')

Helen Curtis Azalea is a compact evergreen azalea that covers itself with crisp white blooms in mid to late spring. Dense, glossy foliage and a naturally rounded, low habit make it a refined choice for foundations, borders, and woodland edges.

Distinctive Features
