Autumn olive is a deciduous shrub from 0.9 - 6.1 m in height. Leaves are dark green, alternate, oval to lanceolate, and un-toothed. The underside is covered with silver-white scales. Small, light yellow flowers are abundant and occur in clusters near the stems in May to June. Fruits are red to pink, juicy, and edible. The small fruits are dotted with scales, and produced in great quantity (about 8 lbs/shrub). Plants flower and develop fruits annually after reaching three years of age.
