2018 Tree Collecting Grants Awarded

We are pleased to announce that eight collaborative projects have been awarded funding this year through our Association’s Tree Gene Conservation Partnership with the US Forest Service. Six of these scouting and collecting projects target at-risk oak species in the wild: Quercus ajoensis, Q. cedrosensis, Q georgiana, Q. sadleriana, Q. toumeyi, and Trans-Pecos oaks in Texas.  Two island endemics, Lyonothamnus floribundus subspecies floribundus on Catalina Island, and Pritchardia minor on Kauai, will also be targeted.  

Rhododendron (North American Native Azaleas)

The Connecticut College Arboretum was established in 1931 as a place to grow and display native plants at a time when exotic plants were more valued in the gardening world. The arboretum was open for the enjoyment of the public and used for teaching by the college’s botany department. The focus was to assemble only those trees, shrubs, and woody vines that are native to eastern North America which can be grown successfully in southeastern Connecticut. Our southern New England climate is well suited for native azaleas.

Tropical Conifers

As Montgomery Botanical Center’s founder, Colonel Robert Montgomery’s first botanical passion was conifers, and by the 1930s he had established an extensive conifer collection at his estate in Cos Cob, Connecticut.  In 1938, after relocating to Miami, FL, he brought an extensive list of conifer taxa to the property that is now Montgomery Botanical Center (MBC).

Pierce's Trees

The Pierce's Trees collection was originally developed by the Peirce family, the original landowners of the property where Longwood Gardens now exists. The collection consists of 276 accessions comprising 50 taxa of woody plants planted from 1798 to 1880 and is composed primarily of U.S. native and introduced species that were available during that time period.


The chrysanthemum collection is a grouping of Chrysanthemum × morifolium cultivars of primarily Japanese origin and is integral to the mission, legacy, display goals, and plant collection at Longwood Gardens.  It is the centerpiece of the yearly Chrysanthemum Festival, a major programming event in the Longwood Conservatory.  Cultivars in the collection were bred specifically for use in at least one of four Asian (mostly Japanese) cultural techniques: bonsai, cascade, thousand blooms
