    Members' Plant Giveaway

    The Members' Plant Giveaway is almost here! Our thank-you event for the Friends of the Arnold Arboretum will be held at the base of Bussey Hill on Saturday, September 17 from 10am to noon. This annual event offers members an opportunity to select a quantity free plants based on membership level, engage staff plant experts, and participate in free drawings for choice specimens from the Arboretum nursery. The Giveaway also provides a great chance to visit the landscape at the close of summer and enjoy a fun-filled morning with fellow plant enthusiasts. Join or renew today to take part.

    Take a Class: From Fungi to Garden Design
    New England Fungi

    Take a class at the Arnold Arboretum and discover new pathways to a greater appreciation of plants, gardens, and local ecology. On September 18, mycologist Lawrence Millman will utilize the Arboretum landscape as an expeditionary classroom for the study of New England's fungi species. Beginning September 20, learn the fundamentals of botany in 10 weekly sessions under the guidance of Harvard botanist Kanchi Gandhi at the Harvard University Herbaria. Ted Elliman of the New England Wild Flower Society presents a September 30 class to help you learn the identity, ecology, and best control options for common invasive plants in our area. And be sure to register early for a special two-day master design class this October 19 and 20 with Rosemary Alexander, founder of the English Gardening School in London.

    Best Practices for Tree Care and Storm Clean Up
    Tree Care

    Just as people with strong immune systems are less likely to get sick, healthy trees with good structure are less likely to suffer damage in a storm. The Arboretum's Landscape Management Plan outlines a schedule for pruning mature trees and shrubs to remove dead, diseased, and broken limbs, and advises structure pruning for young plants to encourage a healthy growth habit. The value of this careful approach is demonstrated by the fact that the Arboretum lost only six trees in last weekend's severe tropical storm. Manager of Horticulture Steve Schneider discussed storm clean up at the Arboretum and offered tree care advice to homeowners in an interview on Martha Stewart's "Homegrown" radio program.

    Library Introduces Collection of Children's Books
    The Tree Book

    The Arnold Arboretum Horticultural Library added a new collection to its shelves this summer. Visitor Education staff selected a number of children's books from titles recommended by the Council on Botanical and Horticultural Libraries. The Arboretum's growing collection of children's literature features popular and award-winning books about plants, animals, and nature. Since the books are for in-library use only, the collection offers great opportunities for a rainy day activity or thoughtful browsing for kids of all ages. The library is located in the Hunnewell Building and is open from 10am to 3:45pm, Monday through Saturday.

    Plant Spotlight on Acer rubrum 'Schlesingerii'
    Acer rubrum 'Schlesingerii'

    Acer rubrum 'Schlesingeri', a cultivar of red maple growing directly across from the Hunnewell Building, is typically the first maple to change color each fall at the Arboretum. Founding Director Charles Sprague Sargent discovered the original plant growing in his neighbor's Brookline yard, and grafted accession 3256-A from budwood he collected in 1888. The tree features rich red to reddish purple foliage in early fall, and usually begins turning color in late August. Now more than 120 years old, the tree stands 65 feet tall with nearly an identical crown spread. Efforts to conserve this important lineage through rooted cuttings have resulted in another individual growing alongside Faxon Pond. Read more about this maple and efforts to broaden its availability in a recent Arnoldia article.

    Artists in the Arboretum: JPOS Exhibit Opens 9/21

    Each September, the Arboretum joins forces with Jamaica Plain Open Studios to present works inspired by the beauty and grandeur of the Arboretum landscape and living collection.

The juried show features a diverse selection of paintings, photographs, prints, and mixed media pieces. Jamaica Plain Open Studios runs from 11am to 6pm on September 24 and 25, but this exhibition will be on view through October 23.

    US and China Scientists Ponder Global Changes
    Lambir, Malaysia

    In an effort to expand understanding of the biological diversity of forests worldwide, Arboretum scientists monitoring a global network of 41 forest research plots have begun a new collaboration with a similar network based in China. This summer, scientists with the Center for Tropical Forest Science, a joint program of the Smithsonian Tropical Research Institute and the Arnold Arboretum, hosted a 17-day workshop and three-day symposium with Chinese scientists in support of coordinating their efforts in studying forests worldwide. Led by Stuart Davies, director of CTFS, the collaboration is made possible through a five-year National Science Foundation grant that will help to finance workshops, travel, capacity building and scientific exchanges. Teaming up is possible because the networks utilize the same research methodology, allowing comparative analysis of data on forest composition, dynamics, and resilience to the effects of global climate change.
