Dr. Rosanna Freyre

Ornamental Breeding and Genetics

Dr. Freyre develops new annual and perennial cultivars of ornamental plants. She uses classical breeding methods of hybridization and selection, and also develops polyploid plants using chemical treatments.  During her career, she has released new cultivars of Anagallis, Browallia, Nolana and Ruellia that are commercially available.  Her current focus is to develop new cultivars of Ruellia that have highly reduced fertility and are non-invasive through seed dispersal in a variety of flower colors and growth forms.
