Osoberry, sometimes called “Indian-plum,” is the first native shrub to leaf out and flower in the spring. It’s often the only flower that early-emerging bees can use for food. Though the small, purple plums that female osoberry shrubs produce in the summer are bitter and astringent, birds love them. Some people say the crushed leaves smell like watermelon! Highly adaptable, osoberry can be placed virtually anywhere in the garden, though it prefers dappled sunlight and moderate moisture.
