As the state flower of Washington, rhododendrons hold a special place in our heart here at Vander Giessen’s. With their love of our mild, wet winters, evergreen foliage, and showstopping blooms in spring, rhododendrons are a must-have for any Pacific Northwest garden. And while many gardeners have unpleasant memories of overgrown, ugly rhododendrons in their yards as kids, many of today’s varieties–and the vast majority of the selections we carry–are more compact and have stunning flower colors not seen in the varieties of generations past.
Rhododendrons love partial shade, but most of the varieties we sell will grow well in full shade to full sun, especially with adequate watering. To keep your rhododendrons lush and healthy and to promote abundant blooms, we recommend feeding twice a year with Espoma Azalea-Tone–feed in early spring before blooming and again in late spring or early summer after the flowers are finished.
