Description

Dwarf buttonbush! Buttonbush has long been prized as a native, but it was way too big for most landscapes. Not anymore! Sugar Shack® cephalanthus is half the size of conventional varieties, making it much more friendly to residential landscapes. Large, fragrant, orb-shaped blooms in summer become ornamental red fruit, which persists through fall. Glossy foliage and widely adaptable. Winner of the Pennsylvania Horticultural Society Gold Medal in 2024.
