Rhododendron and azaleas come in a wide range of colors and foliage.  In their beauty they surpass virtually any other plant in the landscape.  If you are interested in learning more about growing and collecting rhododendrons and azaleas, the American Rhododendron Society is just the right society for you to join.  Its activities include national and regional meetings, publication of excellent journals, scientific studies and research.
Greater Philadelphia Chapter is one of the many chapters of the society.  Our chapter sponsors flower shows, plant sales, cut flower competitions (truss shows), annual banquets, picnics, program meetings with expert speakers providing exchange of advice and expertise as well as good fellowship among fellow gardeners. 
Every year, volunteers from our chapter collect cuttings of native and hybrid rhododendrons from the gardens of members and friends of the chapter.  We root the cuttings and later transplant them into four-inch pots.  We then sell these rare, unusual and generally unavailable varieties at a minimal cost to our members at our Plants for Members sale.  We have also begun to propagate some varieties by grafting and offer these for sale.
In case you were wondering, azaleas are rhododendrons. In botany, the genus is Rhododendron, with roughly 1,000 species and uncountable hybrids. The genus is divided into four sets of garden plants: large-leaf rhododendrons (the classic, also known as elepidotes), little-leaf rhododendrons (lepidotes), evergreen azaleas, and deciduous azaleas. There is a fifth group of rhododendrons, vireyas, which are tropical plants with growing conditions similar to those of orchids.

Rhododendron Society Meeting: Beautiful new cultivars ARS registrar to explain his task, with numerous knockout photos.

SUNDAY, JANUARY 11 | 2:00pm
Free; held at Widener Visitor Center, Morris Arboretum. Philadelphia, PA.

Michael Martin Mills hopes to wow you with stunning pictures of what’s really behind the concept of registering rhododendron names: the beautiful flowers themselves. Since he took over the job of North American registrar from Jay Murray in 2012, Michael has become steward to a trove of electronic images. He will make use of that collection as the speaker at the chapter’s January meeting, with a presentation titled “Name That Clone!”

In addition to floral portraits (have you ever seen ‘Teton Twilight’, ‘Sunset Gold 50’ or ‘Whisper White’?), Michael will explain just what registration is and why it matters. If you have a plant worthy of propagation, in need of a protected name and registration, this meeting is for you.

The meeting will be held in the Widener Visitor Center of Morris Arboretum. Gather at 1:30 p.m. for friendship, coffee and tasty items, with the program beginning at 2:00pm.
