The OPGC's backyard offers a colorful and enticing view from the beautiful new green roof installed on Howlett Hall as part of the Chadwick Arboretum and Learning Gardens' programs. The view from this roof includes our high tunnel and the many raised beds that this year, 2014, are teeming with phlox of many types. The phlox collection includes plants derived from material collected in the wild, as well as representative cultivars. In addition, there is a diversity of interspecific hybrids that have been generated to assess the compatibility between the various Eastern USA native species of Phlox.
