Join Arnold Arboretum docent Rhoda Kubrick on Saturday, April 30 at 1 pm for this tour of the Arboretum’s large maple collection and adjacent Bradley Rosaceous Collection (rose garden). The tour combines a discussion of plant families and origins with the enjoyment of springtime — new leaves and flowers. If time permits, you will climb Beech Path to Explorers Garden and see another wonderful paperbark maple. In case of inclement weather, contact 617.384.5209. Free. Meet at the Hunnewell Building.
