Slightly fragrant and exceptionally cold hardy, Rhododendron 'Karens' is a very eye-catching, dense, and compact, semi-evergreen Azalea. In mid to late spring, it bears abundant clusters of 3 to 4 large, open, funnel-shaped, rich reddish-purple flowers, up to 2 in. wide (5 cm), elegantly darker freckled. The foliage of elliptic, glossy, olive green leaves takes on wine-red and coppery shades in fall and winter. A very reliable performer, this showy Azalea is tough and can withstand temperatures as low as -25ºF (-31ºC). It is said to tolerate neutral soils.
