Shrubs
Rhododendron x 'Karen'
Karen Azalea
Rhododendron x 'Karen' is an evergreen azalea that blooms in spring, with clusters of pink to lavender-purple flowers that may show red color and spotting in the throat. The blossoms are lightly fragrant and sit above small, glossy leaves that stay neat through the growing season. As temperatures cool, the foliage often turns burgundy to red-purple, adding winter color.
'Karen' comes from the Gable Hybrid program, developed from hardy evergreen azalea species.

Design tip
Choose a location where ‘Karen’ can contribute beyond spring, allowing its burgundy winter foliage to enliven a quieter part of the garden. Its compact evergreen form also works well among deciduous shrubs, maintaining fullness after neighboring plants lose their leaves.
