Additional Information

The Catawba Rhododendron is considered to be one of the hardiest rhododendron species. Beautiful plant when it is used in mass. Flower color of the species does not combine well with some other flower colors. Flower color bleaches out in high pH. Subject to winter burning of foliage in exposed sites near the limits of its range. Both flowers and foliage are of equal value in the landscape. Cultivars are usually less hardy than species. Susceptible to a large number of pests and diseases, which can largely be prevented by good cultural practices.
