Schrenk mock orange is native to eastern Siberia, China and Korea where it grows on wooded hillsides and open stream banks. It bears large fragrant single creamy white flowers in May to June. In general it is a medium-sized deciduous shrub, growing to about six feet in height and in width with gently arching branches, but can sometimes reach ten feet in height. While this shrub is adaptable to a range of conditions, it prefers sunny locations and consistently moist soils, and cannot tolerate poor drainage. Plant this shrub where the canes can arch gracefully and the scented flowers can be appreciated. It makes a wonderful screen or hedge or backdrop to a sunny border. Prune back after flowering and cut back to the ground if very overgrown.
