Welcome back to Casey Trees’ third annual Phenology February, our riveting March Madness-esque bracket competition where your favorite trees go head-to-head to see which tree is #1 in the District!

The third round of voting ended, with the American Elm and Willow Oak out of the running.

The fourth and final round is a match-up between the Eastern Redbud and Red Maple.

Who will take the prize?! The final round of voting runs now through Sunday, March 1!

Voting for Phenology February also signs you up to receive Casey Trees' Leaflet, a weekly newsletter carefully curated to bring you information about all things trees in the national capitol region. Don't worry, you can always opt out later.
