Never-Ending Flowers
Shrubs that Break the Rules
and How They Do It
BY PHILIP RONALD

Dr. Philip Ronald studied plant breeding and horticulture at the Universities of Manito-
ba and Saskatchewan. He divides his time between teaching ornamental horticulture at
the University of Manitoba, managing a 20-acre fruit farm, and supporting the research
and marketing programs at Jeffries Nurseries in Portage la Prairie, Manitoba.
