I traveled to Madison, Wisconsin, this week for a water symposium on the university campus. As I walked back to my hotel from the event, I passed the university’s botany garden. On a whim, I meandered off course a few steps and entered.
Although it was too early in the season for everything to be blooming, enough flowers were showing to keep me moving through. Sculptures with botany themes were scattered throughout the small but pretty garden.
One plant and plaque stopped me in my tracks: a picturesque apple tree surrounded by a fence. The tree sported white blossoms and looked older than its 23 Years. Reading the sign, I learned that the tree, planted in 2001, is a direct descendant of the original tree that bore the fruit which inspired Sir Isaac Newton’s Theory of Gravitational Forces.
Huh. I always assumed that the whole apple falling on Newton’s head thing was a myth. But now here was living proof that the tree from which said apple fell not only could be identified, but its offspring was living in Madison!
The plaque said the original “Newton Apple Tree” grows on the grounds of the National Institute of Standards and Technology. But that institute is in the United States (in Maryland). I thought Newton made his discovery in England.
So, in writing this post, I did some digging. The institute tree the Madison tree is grafted from was a clone. Alas, the clone fell over and died about a year ago “due to unknown reasons” according to Wikipedia.

The actual original Newton tree grew in the 1600s on the grounds of the English manor where Newton was raised. The Woolsthrope Manor tree has died, but its descendants and clones live on at the manor and many other places around the world.
The story of the apple inspiring Newton’s theory gained public visibility when Newton’s niece related it to Voltaire, who included it in an essay. The apple, however, did not fall on Newton’s head. That is a silly myth.
The Madison tree was planted in honor of F. James Sensenbrenner, chair of the U.S. House of Representatives Committee on Science (1995-2000). Sensenbrenner was a Republican congressman from Wisconsin and a graduate of UW-Madison. From the plaque text, it sounds like Sensenbrenner presented the tree to the university himself in hopes that “the fruit of this descendant inspires others to partake in scientific discovery.” This strikes me as rather self-aggrandizing, but it was a nice gesture, no doubt accompanied by some additional funds.
As if having a copy of the Newton tree isn’t enough, the UW-Madison Botany Garden was the first in the world to be based on the new Angiosperm Phylogeny Group system of molecular classification of plants. I don’t really know what that means but if you visit the garden’s webpage, there’s a chart about that.
As I continued my walk through the garden, I envied the Madisonians their warm breezes and blooms. In northern Minnesota, our daffodils are just beginning to show. It will take us about three weeks to catch up to the plants in Madison. Sigh. But this way, lucky me experiences two blooming seasons and that’s just fine.
I exited the garden, glad for my little educational and botanical detour and that I’d have something to share with you. And now you know more than you probably ever wanted about Newton’s apple tree!
