Because of the elderberry’s ability to grow in most American climates, the options for companion planting are nearly endless. Try planting other sun-loving berry shrubs near your elderberries — blueberries, winterberries, and currants are all good choices. Alternatively, you can add a few additional cultivars of elderberry, such as Sambucus nigra ‘Black Lack’, to enjoy an even greater variety of fruiting times and flavors. Avoid planting too close to shady trees, as this will prevent ‘Johns’ and ‘Adams’ elderberries from reaching their full potential.
