From patent application (inventor Robert Mark Saul):

"The new Coreopsis originated from a cross-pollination made by the Inventor in Atlanta, Ga. in May, 2002, of the Coreopsis auriculata cultivar Zamfir, not patented, as the female, or seed, parent with the Coreopsis lanceolata cultivar Early Sunrise, not patented, as the male, or pollen, parent. The new Coreopsis was discovered and selected by the Inventor as a single flowering plant from the within the progeny of the stated cross-pollination grown in a controlled environment in Atlanta, Ga. in May, 2003."


My Experience: 

I purchased a 4" pot from Santa Rosa in September 2010 and planted it in the Octagonal Perennial Garden. It did well in spring 2011 through summer but did not return in spring 2012.
