Rhododendron Notes

After the name of each rhody or azalea, we have listed a series of numbers. First is the size of the plant in 10 years. Then, hardiness ratings in degrees Fahrenheit. Bloom times in our area:

• VE- Jan-April 1
• E- April 1-May1
• EM- May1-May15
• M- May 15-June1
• ML-June 1-June 15
• L- June15- July 1
• VL- July 1- Aug

Our descriptions also include American Rhododendron Society ratings when possible. The three numbers (i.e. 3/4/4 ) rate the flower, plant, and performance in the garden. A ‘5’ is an excellent, but uncommon, rating. ‘3’ ratings are common, but a lower rating does not mean the plant is not worth growing. ‘-/-/-‘ indicates a rhododendron that has not yet been rated by the ARS.
