Dr. Richard Criley is a Emeritus Horticulturist with the University of Hawaii and specializes on tropical plants, particularly those found in the Hawaiian Islands. His main interest seems to be directed to those plants that flower. He has published several articles on plumeria.
I will throw another name out, and this would be directed more to the Houston, TX plumeria growers. Do any of you know who Eulas Stafford is? Dr. Criley told me to contact him about Slaughter Pink color break.
