Summary
The big, dependable rhododendron that has filled shady yards for generations.
Roseum Elegans is one of the old “ironclad” rhododendrons, the group of large-leaf hybrids that proved tough enough for cold northern winters, and it is still one of the most widely planted. Its staying power comes from reliability: it flowers year after year in conditions that would sulk lesser rhododendrons, including colder winters, warm summers and soil that is less than ideal.
In late spring it carries large, rounded trusses of rosy lilac flowers across the whole shrub. Bloom arrives as spring turns toward summer, after most azaleas and early rhododendrons have finished, which helps carry color into a quieter part of the year.
It is a large plant. Over time it grows into a dense, upright mound of dark green leaves six to ten feet tall and wide, big enough to screen a neighbor's view, hide a fence, or fill the space beneath tall oaks and pines. Few broadleaf evergreens give that much year-round cover in partial shade.
Care
Roseum Elegans Rhododendron Care
Plant in partial shade. Dappled light under tall trees or a site with morning sun and afternoon shade suits it best. Too much hot afternoon sun can bleach and scorch the leaves, while deep shade reduces flowering.
It needs acidic, well-drained soil with plenty of organic matter. Like all rhododendrons it has shallow, fibrous roots that rot in waterlogged ground, so avoid low spots, amend heavy clay generously, and keep the top of the root ball level with or slightly above the soil surface.
Water deeply once or twice a week through the first growing season and during dry spells afterward. A two-to-three-inch layer of shredded bark, leaf mold or pine needles mimics the woodland floor it prefers and keeps the roots cool and moist. Avoid digging around the base.
Feed lightly in early spring with a slow release fertilizer. Plants in good woodland soil often need little or none.
Prune only right after flowering, since flower buds for the next year form during summer. Older, overgrown plants can be renewed by cutting a few of the oldest stems back hard after bloom, spread over two or three years.

What Size is the Roseum Elegans Rhododendron for Sale Online?
Our Roseum Elegans Rhododendron ships in a greenhouse-grade grow pot and is appropriately sized for its container at the time of shipment. As an evergreen it ships with its leaves on, and in the off-season it may arrive with next spring's flower buds already set. If you have specific sizing or planting questions, please contact us.
How Large Does Roseum Elegans Rhododendron Grow?
Expect about 6 to 10 feet tall and 6 to 10 feet wide at maturity, in a dense, upright, rounded shape. Growth is moderate, so it takes a number of years to reach full size. Give it room: space plants about 6 to 8 feet apart for a screen, and keep it well away from windows and walkways.
Additional Information
What is an ironclad rhododendron?
Ironclad is an old nursery term for the large-leaf rhododendron hybrids that proved they could survive cold northern winters and still flower reliably. Roseum Elegans is one of the best known of the group and remains a standard choice wherever winters are hard on broadleaf evergreens.
Can it be used as a privacy screen?
Yes. At six to ten feet tall and wide with dense, evergreen foliage, it is one of the few flowering shrubs that can screen a view in partial shade. Plant in a staggered row 6 to 8 feet apart and allow several years to close the gaps. See more options in our Privacy Trees & Shrubs and Evergreen Plants.
How much sun can it handle?
It is happiest in partial shade. It tolerates more sun in cool northern gardens, but in most areas full afternoon sun leads to yellowed or scorched leaves. A spot beneath high tree canopy, or on the east side of a building, is ideal.
Do deer eat it?
Deer do browse rhododendrons, especially the buds and leaves in winter, and a large planting can take noticeable damage where deer are common. Protect plants with fencing or repellents in high-pressure areas, or choose from our Deer-Resistant Shrubs and Evergreens.
