JARS v41n2 - Azaleas In The Philadelphia Area
Azaleas In The Philadelphia Area
William F. Steele, West Chester, Pennsylvania
"The temperature is -10° F. with a wind chill factor of -40 to -50° F. Most Linwood's do not do well out here". This was a response to a recent survey conducted by the Azalea Study Group representing the ARS chapters in the Philadelphia region. This survey resulted in an almost complete cataloging of the azaleas being grown in the Philadelphia area and a listing of "The Most Highly Rated Azaleas in the Philadelphia Area".
The Azalea Study Group is a committee composed of those members of the Valley Forge, Philadelphia, and Pine Barrens chapters who have a special interest in azaleas. In addition to holding meetings to share information, they have been involved in the study and evaluation of azaleas, the development of display and test gardens, an annual evergreen cutting exchange, an occasional deciduous cutting exchange, and an azalea flower show.
The survey mentioned earlier was one of the projects undertaken two years ago. It was the study group's intention to have the membership of all three chapters list and evaluate the azaleas they are growing. An initial attempt, a form on which the members were asked to enter the names of the azaleas, then evaluate them, proved unsuccessful.
The study group felt better results might be obtained if the members were provided with a list of azaleas and could select the plants they wanted to rate. Subsequently, the members in the three chapters were asked to submit a list of the azaleas they have been growing in their gardens for three or more years. The results of this request, an almost complete listing of azaleas growing in this area, was submitted to the membership. In spaces provided to the right of each name, they were instructed to rate the flower and plant habit on a scale from 1 to 5. These results were used to determine the ranking of "The Most Highly Rated Azaleas in the Philadelphia Area".
Although the response to the final evaluation was better than the initial one, it was not possible to do a formal statistical evaluation of the results. Therefore, the listing of "The Most Highly Rated Azaleas in the Philadelphia Area" could be subject to as light reorganization if the results were interpreted differently. The most significant achievement of this project was an almost complete listing of azaleas currently growing in the Philadelphia area.
The Philadelphia area was considered to extend as far north as Reading, Pennsylvania and as far south as Linwood, New Jersey, roughly within a sixty mile radius of Philadelphia.
The U.S.D.A. Plant Hardiness Zone Map places the Philadelphia region in Zone 6b to 7a with average annual minimum temperatures of -5 to 5° F. The lowest temperatures occur in the northern and western sections. Usually the temperatures do not reach these lows. However, there are occasional years when the temperature drops below these averages. In January 1984 there were four consecutive days of below zero weather. During this period the lowest official temperature recorded in the western suburbs was -16° F. That particular morning one of the members living north of Reading thought his thermometer was broken when it read -24° F! Upon buying a new thermometer, he found it read the same as his old one. Most plants on the list of azaleas in the Philadelphia area lived through that cold spell; most of the buds did not.
Not all the plants on the list are hardy in the northern and western sections. Even within a few miles of Philadelphia, some plants struggle and only reward their growers with a sparse bloom after an occasional mild winter. Some of the Linwoods will not grow in the northern and western sections, although 'Hardy Gardenia' has proven itself to be dependable in all sections. The Carlas on this list usually will not produce a complete bloom.
Azaleas in this section bloom from April 10 until the end of June. The blooming periods are considered to be: early, April 10 to May 5; mid season, May 5 to May 20; and late, May 20 to June 30. The peak period of bloom is from May 10 until May 25. The late blooming azaleas are the Robin Hills, Satsukis, and North Tisburys, some of these occasionally lasting into July. There are three fall blooming azaleas in the area, 'Opal', 'Indian Summer', and August to Frost (a single white we are still evaluating). These usually bloom from late September until frost.
Until recently the average gardener's choice at local garden centers was limited to 'Delaware Valley White', 'Hino Crimson', 'Hinodegiri', 'Hershey's Red', 'Coral Bells,' tradition', and 'Purple Splendor' or 'Herbert'. There is now a trend for the larger, better quality garden centers to carry a greater selection of plants. It is possible for the average gardener to find nearly 100 varieties available by shopping at different garden centers. Selections from the Glenn Dales, Robin Hills, Girards, North Tisburys, Gables, Shammarellos, Linwoods, and Satsukis are now available. It is even possible to buy unusual plants such as 'Silver Sword', Chinsayi*, 'Kaempo', R. vaseyi , R. schlippenbachii , R. prunifolium , and R. periclymenoides . One progressive garden center is adding ten new varieties per year. One of the large growers in the area is now growing 'Hardy Gardenia' as his basic white azalea. The average gardener may never be able to select all the azaleas from the list of "Azaleas Growing in the Philadelphia Area", but his options are increasing.
* Chinsayi: A shiny leaf compact dwarf that faithfully covers itself with 2½" pink blossoms. Mrs. Julian Hill obtained it from Dr. Rokujo's garden. For lack of a better description we have listed it as Rokujo's to distinguish it from the Satsuki hybrid 'Chinsayi' (synonym Hana Fubuki).
