ALBUM CATAWBA RHODODENDRON
Rhododendron catawbiense 'Album' is commonly referred to as Catawbiense Album Rhododendron or Catawba Album Rhododendron. This is a cold hardy Rhododendron variety with excellent bright green foliage and pale lavender buds that open into attractive pure white flowers that have greenish-yellow blotch.
Catawba Album Rhododendron is incredibly hardy. It thrives in partial shade and grows extremely well as an understory shrub - morning sun with afternoon shade is perfect. It enjoys rich, fertile, evenly moist, well-drained soils and benefits from wind protection. 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.
