More than 2500 trees—over 130 different species and varieties—provide a shady canopy, beneath which thrives a layered understory of flowering trees, shrubs, ornamental grasses, and seasonal plantings. Beds display bold arrangements and striking combinations of plants, all carefully selected by our landscape architects and tended by staff arborists and horticulturists. Throughout the arboretum, you will find an array of pleasing features and unexpected spaces—sculpture gardens, pocket parks, ponds, and streams—that invite you to pause, for contemplation or conversation.
