This is Yaku Princess...My favorite. Rhododendron loves a bit of shade, but does remarkably well in sun as well. Many huge plants have dazzled us over the years in full sun to become the size of houses. This is a small plant and began it's bloom early...Two weeks later, the rest of my Rhododendrons are just coming out in the last week of May. Woodland understorey plants grow wild in New England.
