A deciduous shrub, it can grow to 8’ tall & has a delicate appearance with small Maple-like leaves & attractive white 3-5” flower clusters in the Spring. The leaves turn red-orange in the Fall & the common name “Ninebark” describes the distinctive bark which peels to show many layers at the same time. Pretty! Combine with other woodland plants like Aquilegia Formosa & Heuchera maxima. Will need more water if grown in sun in inland gardens.
