Connections!
* Hawthorns line College Road at Wellesley by the Founders Hall parking lot. They were chosen because of their picturesque tracery of branches, which adds beauty to the winter landscape.

* In Europe, hawthorns are often pruned into hedges and made into fence posts. The word "haw" has the same origin as the word "hedge."

* The hawthorn's dense branches are popular nest spots for many songbirds. The trees are valuable as honey trees for bees to pollinate, and they provide food for cottontail rabbits, white-tailed deer, and many wild birds.

* The hawthorn fruits in the center photo appear hairy and orange because they are infected by a fungal disease.
