On September 11, 1998, I discovered a H. macrophylla in full flower at Bailey Nursery's test site in St. Paul, Minnesota (-30 degrees F). Pedigree unknown, found by Vern Black, a Bailey employee, in a neighbor's garden, and growing in the company's test plots for 8 to 10 years. I requested cuttings, was given same, and after controlled testing via Jeff Adkins master's research at the University of Georgia, am convinced this selection, named 'Endless Summer', is perpetual flowering. Bailey Nursery is trademarking the name and working with McCorkle Nurseries, Dearing, Georgia, for a 2003 to 2005 release. Their target numbers are one half to one million plants. |
