Wild Flower Watch

Last Update:

May 22, 2018

Time Covered:

May 8 - 21, 2018


RBG Rose Garden edges, Hendrie Valley, and Arboretum;
Christie C.A., Anita Dutka-Buchin Sanctuary, Brantford Rail Trail,
and a property just west of the Hamilton border


Because this post covers 2 weeks, there are 100 species that were found in bloom. There were 59 new species for the year. Because of the rapidness of the spring weather, some species have already come and gone during the 2 weeks. It is hard to keep up with the changes right now.

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:
