Rhododendron Hybrid ‘Catawbiense Grandiflorum’ – Majestic Lilac Blooms with Year-Round Evergreen Structure

Rhododendron ‘Catawbiense Grandiflorum’ is a classic and robust evergreen hybrid celebrated for its spectacular lilac-purple flowers and its ability to thrive in a range of conditions, including colder, more exposed sites. Flowering in late spring, it forms a dense, rounded shrub with large trusses of soft lavender-purple blooms accented by golden brown markings. This time-honored variety is ideal for providing structural interest, seasonal color, and evergreen coverage in woodland gardens, mixed borders, or as a majestic standalone specimen.
