Rhododendron catawbiense 'English Roseum' is commonly referred to as English Roseum Rhododendron. It is a compact, dense, fast growing evergreen shrub that features large, lavender pink flowers in late spring. Elliptic to oblong leathery dark green leaves stay evergreen through the year.
English Roseum Rhododendron thrives in filtered sun - morning sun and afternoon shade works best. It enjoys rich, acidic, humusy, evenly moist, well-drained soils. It is ideal for shrub borders and woodland areas. Protection from winter winds is beneficial. Any pruning should be done right after flowering.

To help this plant settle in and thrive, we recommend these standard planting practices: Plant in rich, moist, acidic, and well-draining soil, selecting a location that provides partial shade or filtered light to protect the foliage from harsh, direct sun. These shallow-rooted shrubs require consistent moisture to remain healthy, especially during the first growing season until they are fully established. Prune immediately after the flowering period concludes, as new buds for the next year are set shortly after blossoms fade; removing spent blooms and light tip-pruning encourages a fuller, more vigorous habit. Apply a generous layer of organic mulch around the root zone to conserve moisture and regulate soil temperature, ensuring the material remains a few inches away from the crown to prevent stem rot.
