Sambucus racemosa var. arborescens
Red elderberry is a large, deciduous shrub that can easily be pruned to take the form of a small tree. In mid-spring, the branch tips are abounding with fragrant white flowers that provide nectar for butterflies and bees. As spring turns to summer, flowers mature into tiny red berries that are attractive to the gardener's eye and as food for a plethora of backyard birds. Hollow stems provide habitat for mason bees.

Gardening with Red Elderberry: This fast-growing large shrub tolerates a variety of sun and moisture conditions. That said, it will generally require more moist soils in more open and sunny areas. Try it along the edges of your moist woodland, in a ditch, bioswale or raingarden, or in the dry shade under conifers. Its vase-like shape is highly prunable, making it a surprisingly good choice for smaller gardens, along fences and side yards, where it can be effortlessly shaped into a small tree. Note - branches and small sections often die off as quickly as new branches spring forth. Don’t be alarmed as you see branches become leafless and brittle, this process is not only normal, but is creating exceptional habitat for wildlife.
