Summer Sensations at the Washington Park Arboretum

Spring may delight us with color, but throughout the year we can appreciate other sensory elements in Washington Park Arboretum’s collections. Leaves and blooms can give off powerful aromas. Texture and plant shape can provide a sense of drama or reverie. Enjoy all your senses with these plant choices!
