Buttonbush

Buttonbush has long been prized as a native, but it was way too big for most landscapes. 'Sugar Shack' is a breeding breakthrough from Proven Winners. It is less than half the size of the species making it suitable for smaller gardens. Cephalanthus 'Sugar Shack' has interesting  fragrant white flowers followed by shiny red fruit. The fIowers are very rich in nectar making them a valuable food source for pollinators. It also has beautiful glossy green foliage from spring to fall.
