Have had great success with these! I took a chance growing these in full sun as foundation plantings on the south side of my house, (in drought-prone sandy soil) knowing that I'd be pushing my luck doing this. I kept them well watered the first couple years, and they have been amazingly resilient to what most people tell me are less-than-ideal growing conditions. This is their third year in this location and they are currently covered in blooms and seem very healthy even after this past very harsh winter.

This beautiful Rhododendron grows very happily in my moisture retentive partly shady location. This hybrid is very tolerant of extreme cold, heat & humidty. It's rosy-lavender domed trusses are held above the large glossy green & recurved leaves. It is a very vigourous and upright shrub.
