Open Every Day. Free Every Day. | Mid July 2026 Midsummer Magic in the Bradley Garden Looking for a rewarding summer stroll? Discover the Bradley Rosaceous Collection, a five-acre garden near the Forest Hills entrance that showcases the remarkable diversity of the rose family. Roses, cherries, crabapples, serviceberries, mountain ashes, and their relatives from around the temperate world grow side by side, highlighting connections among some of the world’s most beloved plants. In midsummer, roses bloom across mixed beds and spill over the entrance trellis, while spring-flowering trees display handsome foliage and developing fruits. Three picturesque ponds attract dragonflies, turtles, frogs, ducks, and even the occasional great blue heron. This unique blend of horticulture, wildlife, and landscape design makes this landscape a favorite destination for gardeners, nature lovers, and families alike. Drop by the garden on Sunday, July 26 at 10:00am for the Arboretum’s latest Ask a Horticulturist program, where horticulturist Rachel Lawlor will chat about the collection and its year-round care. Learn more online, then visit soon to experience the beauty, scents, and textures of this collection for yourself. Explore the Rose Family Ask a Horticulturist Double Take: Scots Pine What can plants and the works of art that they inspire reveal about one another? Our ongoing series of Double Takes explores that question by pairing a plant from our living collections with a work of art from the Harvard Art Museums, uncovering unexpected connections across time, place, and discipline. In the latest edition, a Scots pine (Pinus sylvestris) growing in the conifer collection is considered alongside Train Smoke, a 1910 painting by Norwegian expressionist artist Edvard Munch. Keeper of the Living Collections Michael Dosmann recognized the distinctive pine depicted in Munch’s landscape and discovered a remarkable coincidence in our plant records: several of the Arboretum’s Scots pines were grown from seed collected near the very shoreline where Munch painted this work more than a century ago. Could the distant trees in Munch’s painting be ancestors of those growing in our landscape today? Check out the full story online, then visit both collections to appreciate the finer details up close.
