Karen holds to Zone 4, which puts it further north than nearly any evergreen azalea will survive. Rhododendron 'Karen' carries lavender-pink flowers that resist fading in sun, growing 3 to 4 feet tall and wide in full sun to part sun, hardy from Zone 4 through Zone 8.
Bloom comes in mid-spring on a dense, rounded plant.
The small leaves are evergreen and turn bronze-purple in cold weather, holding through winter.
Acidic soil is necessary, roughly pH 4.5 to 6.0, with good drainage and steady moisture. Alkaline ground turns the foliage yellow. Mulch the shallow roots. Give it some winter wind protection at the cold end of its range.
