The following is a detailed description of the new Harella cultivar based on observations of one-year-old plants grown together in one gallon containers in a cool greenhouse in March in Canby, Oreg. Canby is Zone 8 on the USDA Har diness map. Temperatures range from a high of 95 degrees F. in August to an average low of 32 degrees F. in January. Normal rainfall in Canby is 42.8 inches per year. The color descriptions are all based on The Royal Horticultural Society
