On February 16, 2018, I monitored our team's three redbud (Cercis canadensis) trees at the Duncans Chapel site in Willis, VA. It was a warm, sunny day (63 F). After a week of unusually warm weather, with high temperatures consistently above 60 F and rain nearly every day, flower buds were clearly visible. On two trees, I estimated more than 1,000 flower buds on each tree! The buds are round and clustered, not yet open, but they are beginning to swell and seem larger than they were last week. Across all of our monitored redbuds, we did not see any evidence of breaking leaf buds or open flowers. I did notice that the redbud in our shadiest site had fewer flower buds and seemed to be developing more slowly. I wonder if it will have fewer flowers -- and fewer pollinators -- since it doesn't get as much sun? (Post by C. Small)
