Answer: Rhododendrons are not as cold hardy as they need to be for your gardening region but there are lots of shrubs you can choose from:
Berberis sp. Barberries, Caragana sp. Siberian Pea shrubs, Cornus sp. Dogwood,
Deutzia sp. Deutzias, Forsythia sp. Forsythias, Lonicera sp. Honeysuckles,
Philadelphus sp. Mockoranges, Spiraea x arguta Garland spirea, Spiraea xi vanhouttei Vanhouttee spirea, Syringa sp. Lilacs, Viburnum sp. Viburnums, Wiegela sp. Wiegela. All will return each spring and most will flower in spring or in summer. Enjoy!
