This planting bed contains two types of bush-honeysuckle. Both species of shrub are part of the Arboretum’s Center for Plant Conservation collections—collections of species for conservation purposes. The species is native to the southern Appalachian Mountains, where it grows on rocky ridges and outcroppings. In spring, this mountain bush-honeysuckle grows its small, green leaves. By mid-summer, small yellow flowers have emerged. In fall and winter, when the leaves are gone, the shrub’s colony-forming structure (growing roots where the tips of its branches touch the ground) can be observed.
