There are several scattered through the moist, pine and hardwood mixed woodlands, dappled to heavy shade. The shrubs get about 6 feet tall, nicely round tops almost like an umbrella, thin woody, multiple trunks. The flowers are fragrant. The shrub is usually near pines. If I remember right the leaves turned muted dark red-green in fall. Photos taken 5-14-2016.
your shrub is a sparkleberry, Vaccinium arboreum, which is a relative of the blueberry but the berries are barely edible. It is rather common in this area. It is undoubtedly a good honey plant for bees.
