The White Catawba is an Ironclad rhododendron bred for cold hardiness by Anthony Waterer of Knap Hill, Surrey, England in the late 1800's. It can handle temperatures down to -30F. Its soft lavender buds open into campanulate, white flowers adorned with a blotch of chartreuse freckles. Dark green lustrous and disease-resistant evergreen leaves are an excellent backdrop for the spring flowers. A dense and vigorous grower to 5 to 6 feet tall and equally as wide, larger over time, White Catawba makes for an impressive eye-catching specimen in partially shaded to sunny woodland or landscape borders. This glorious beauty will always have you looking forward to spring!
