'Boursault' is a very hardy and easy-to-grow native Catawba Rhododendron that can handle temperatures down to -30ºF. She features abundant, large and long lasting clusters of gorgeous lavender flowers with red freckles that open from deep violet colour buds. Dark green lustrous and disease-resistant evergreen leaves are an excellent backdrop for the spring flowers. A dense and vigorous grower up to 10 feet tall and wide, and even larger over time, 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!
