Prized for its tolerance to sun, cold, and humidity, Rhododendron 'English Roseum' is a dense and showy evergreen shrub. From late spring to early summer, 'English Roseum' graces the garden with its profuse, large, dome-shaped clusters of 8 to 10, trumpet-shaped, lilac rose flowers with delicate orange freckles. They contrast beautifully with the foliage of large, smooth, glossy, medium green leaves. A very reliable performer, this pretty late midseason Rhododendron is quite tough and can withstand temperatures as low as -25ºF (-32ºC). This large ornamental shrub is perfect for background plantings or filling areas beneath deciduous trees where it will add elegance and brilliant color.
