Species

 Rhododendron albiflorum Hook. – Cascade azalea

The appearance of this shrub is more like the rhododendrons we term azaleas.

It has small deciduous leaves, reaches 3-6’and has an open branching habit.

Cascade Azalea has a limited range within British Columbia, Washington, Oregon, Idaho, and Montana at sub alpine to alpine elevations along moist forest slopes and stream banks.

The creamy bell shaped summer flowers are replaced by brown fruit capsules that pair up with brightly colored fall foliage.

Not being a poisonous member of the rhododendron family, Native Americans utilized parts of this plant medicinally as a tea or gargle for stomach and throat issues and a dressing for skin injuries.

Grow Cascade Azalea in USDA zones 6-8.
