Photos and Information from Ron Hepworth




Ron passed away on Tuesday, September 4th, 2012. Because he kept records of early and peak blooming times for nearly 30 years and then passed along his summaries to me for this site, I plan on leaving his last summary here. Below is a small sample of what the whole summary looks like:
