If you review planting guides, nearly all of them specify full shade for this shrub. I bought 3 of these plants and put them in full shade. The shrubs languished so badly that I talked to my county horticultural specialist. He told me that for some reason most references do incorrectly list full shade for this species and that I should dig the shrubs up and move them. So I dug them up and moved 2 to full fun and 1 to part sun. Boy, did they recover quickly, and the ones in full sun are now significantly larger than the one in part sun. So full sun and definitely not full shade is what this plant needs no matter what all the books say.
