I bought a plant about two years ago from one of your centers. It's doing great! I'd love to find out more about this plant.
The name on the tag said
|Without seeing the plant, it's impossible to positively identify it, but there is an azalea that matches the color description of the flower. It's Rhododendron catawbiense 'Josephine' and the pink buds open to large, bell-shaped creamy white flowers that are flushed with pink at the tips and lightly spotted red in the throat.
Try a web search on Rhododendron catawbiense 'Josephine' and I'll bet you'll find several photos to compare with the flowers on your plant.
