Why plant English Roseum Rhododendron?
When spring turns balmy and the threat of frost is fading from view, English Roseum Catawba Rhododendron unleashes one of the most spectacular floral shows of the season. Voluptuous lavender-pink blossoms in large and abundant trusses grace its sturdy branches. The pretty flowers make a striking contrast to the thick, leathery leaves—a perfect partnership of rugged and delicate elements. English Roseum will fill up blank spaces in your beds and borders, foundation plantings, and woodland edges with glossy, large foliage that shines all year long. Fun and functional, it’s one people-pleasing Accent! English Roseum is a type of Catawba Rhododendron. From late April through June, the Catawba Rhododendron lights up shady hillsides and forest understory in the Alleghany Mountains, bringing its rosy purple cheer to a region extending from southern Virginia to northern Alabama. English Roseum therefore calls the U.S. home, although as you can guess by the name, it also owes an allegiance to England. It emerged from the long and illustrious Rhododendron (and Azalea) breeding program at Knap Hill Nurseries in Sussex. It was introduced in 1958. English Roseum is very similar to the variety known as ‘Roseum Pink’.
How to use English Roseum Rhododendron in the landscape?
Some Rhododendrons can be a bit tricky to grow, but English Roseum is one of the most resilient. With proper care, it thrives in the colder states—down to -25ºF—and tolerates the heat and humidity of the South as well. This one is a winner!
How To Plant English Roseum Rhododendron
Catawba Rhododendron is tougher than many Rhododendrons, but it does appreciate good siting and aftercare. Plant English Roseum in part shade, in cool, acidic, well-drained soil for best results. Keep the rootzone moist but never soggy. An annual layer of organic mulch will help to retain moisture. Avoid harsh chemical fertilizers—Catawba Rhododendron is sensitive to overfeeding; a gentle organic product like Bower & Branch Elements™ Fertilizer is all that is needed if plants seem weak or “hungry.” Black vine weevil and Azalea lace bug can sometimes be an issue, but specimens grown in optimal conditions in most cases will remain healthy and resistant to attack.
Frequently Asked Questions
The blooms are rosy-lavender, forming large trusses in spring. The color reads soft and classic, especially in dappled light where it looks rich without feeling loud.
It prefers acidic, well-drained soil with consistent moisture. Rhododendrons have shallow roots, so mulch helps keep roots cool and evenly moist, just keep mulch a few inches away from the stems. Avoid soggy soil, but don’t let it dry out completely during heat.
Deadheading spent flower trusses after bloom is optional, but it can keep the plant tidy and support strong growth for next year. If shaping is needed, prune lightly right after flowering. Avoid heavy pruning late in the season, since buds for future blooms develop on new growth.
