Autumn Brilliance

Amelanchier x grandiflora 'Autumn Brilliance' (am-uh-LAN-kee-er)

Family: Roseaceae Native Understory (15-40 ft)

Serviceberry is in the rose family (Rosaceae), native to Europe, Africa, North America, and temperate Asia. The genus name is taken from the Savoy common name for a European species. Serviceberry is one of the first shrubs to flower in the spring, just before the dogwoods. It acquired the common name serviceberry because it blooms as soon as the ground starts to thaw, when people were able to dig graves and bury their dead after the winter. It also derives the common names of shadbush and shadblow from the fact that the masses of flowers tend to open at the same time that shad ascend the rivers in early spring to spawn. Serviceberry is a multitrunked shrub or small tree with a rounded crown and grows 15 feet tall. Most species require full sun or partial shade, and they are adaptable to a wide range of soil and pH conditions. Plants in deeper shade may not flower well, but they will survive. It forms root suckers, and if they are allowed to grow, it will result in the plant growing as a shrub rather than a tree. Over time, the suckers will cause the plant to form a small colony. Pruning should be done in the fall in order to avoid excessive loss of sap. It does well in a broad range of areas, from lawns, patios, and ponds to meadows and woodlands. Include it in edible, native, pollinator, or drought-tolerant gardens as an accent plant, shade tree, or screening hedge. Insects, Diseases, and Other Plant Problems: Fire blight and fungal leaf spot may affect the plant’s overall health. Rust and powdery mildew are also issues. It becomes chlorotic in alkaline soils and does not tolerate wind. The flowers, and later fruits, dropping on the ground can become a maintenance issue. Rabbits will often destroy the seedlings.
