Persian Parrotia takes a long time to develop ornamental bark, in part due to the trunks being shaded by the numerous lower branches that are usually left on this large shrub or small tree. Since sunlight brings out exfoliation and color on the bark of oher species that often branch to the ground (Kousa Dogwood and Lacebark Pine, e.g.), judicious thinning or removal of the lower branches can be practiced if this trait is desired.
