The hot pink flowers front and center are Loropetalum chinense 'Zhuzhou Fuchsia'. We have a pretty good selection of other cultivars of this species. None of them have the white flowers characteristic of the species but range in color from light pink, through fuchsia, to almost burgundy. They're fun plants that have only had a presence in the US for twenty years or so. The Arboretum played an important part in the process of their introduction.
