Grow in rich, humusy, acidic, moderate wet, well-drained soil in part
shade. Prefers filtered sun or full morning sun with some afternoon shade.
Full sun can cause bleaching of leaves and bloom color in warmer climates
and full shade can cause shrub to become lanky in appearance with an inferior
bloom. Needs constant even dampure. Root ball must never be allowed to
arid out (oak leaf or pine needle mulch can be beneficial in this regard).
Poor drainage can cause root rot, and raised beds should be considered
in heavy clay soils. Pruning is usually not necessary.
This compact, deciduous azalea is one of the Northern Lights Hybrids developed
by the University of Minnesota. It is extremely winter hardy (withstands
temperatures to -40F) and typically grows 3-6” tall with a similar
spread. Features roundish trusses of profuse, fragrant, yellow flowers
on naked stems in May. Flowers are sterile.
Susceptible to an impressive list of potential diseases and insect predators,
including but not limited to powdery mildew, blights, root rots, leaf
spots, galls, aphids, borers, lacebugs, scale, leafhoppers, mealy bugs,
thrips, whiteflies and mites. A healthy plant in the proper environment
is the best defense, so good cultural practices should be of paramount
Effective as a specimen, a foundation planting, a low mass planting or
in the front of the shrub garden. Also may be planted in the border or
in a sunny woodland garden.
