Proven Performers: District 6

The ARS Public Education Committee in 2000 asked chapters to compile lists of the best performing rhododendrons in their areas. Not only were these to be plants with good form, foliage texture and flowers, but also they were to be cold and heat hardy for the area and resistant to pests and diseases. The integrity of the lists is based upon the fact that the plants have proven their ability to perform well in members' gardens. The response to the request was overwhelming with almost all chapters sending lists to the committee. As a result, the Society and its chapters are able to make these lists available to the public to guide them in selecting rhododendrons that do well in their local area.

The chapters were asked to list ten each of elepidotes, lepidotes, deciduous azaleas, evergreen azaleas and, where pertinent, vireyas. Some chapters followed this procedure, while others included more of one category than another. No matter how the lists were organized, the Society now has a "Proven Performer" list of rhododendrons that do well in specific regions, along with culture tips specific to the area and, in some cases, sources for the plants.

The Journal began publishing the lists in the fall 2000 issue, starting with District 1. The Proven Performers from District 6 are listed in this issue. An asterisk (*) indicates the name is not registered.

Specific to the Connecticut Chapter Region
-Dig planting hole about two times root ball diameter in well drained soil.
-If on a slope, level the area around the hole, put small earth dam around hole.
-If plant is in a pot, check the root mass and break up if necessary. If it is bag and balled, loosen burlap around the ball.
-Plant in hole with approximately 50/50 mix with rotted oak leaves or pine needles and top soil/dirt.
-Water heavily as you go.
-Leave the root ball about 1 inch above the final fill level and give final watering. Water regularly.
-Mulch with bark or rotted wood chips, no lime. Fertilize with 10-10-10 if desired after one or two years.
-Before the final heavy freeze in the fall, water heavily. Water regularly in summer until established.
