I have a Cornus Alternifolia "Golden Shadows" that I've grown from bareroot since 2010. This will be it's 3rd season in the ground - see pic. I really like it, but thought it may be 4 or 5 feet by now. It seems to grow very slowly. Does anyone have any experience with this tree? It's in a spot where it gets about 4 or 5 hours mid-day sun and some dappled sun in the late afternoon. Is that perhaps too much? I know they like some shade and I thought 4 or 5 hours was really "part shade". Any input would be really appreciated!
