2012-05 May

Flowers I have seen blooming between 2 May 2012 and 1 June 2012.

Blooming data are based on my personal observations between 2010 and 2012. They are not perfect.

The red bits of the little tables under the flowers indicate when I observed those flowers blooming. The fainter red bits indicate months in which the flower bloomed but for which I neglected to record an exact start (or stop) date. Since these are the observations of one man randomly walking the local trails I may have missed the true start/stop by several weeks.
