2022 Acorn Watch: Overcup Oak (Quercus lyrata)

Overcup oak acorns are ripening. On the tree, we see both the acorn and its cap turning from green to brown, and in the leaf litter we see fully ripe acorns. All of the photos below are from October 30, 2022.


Two acorns have turned brown, indicating ripeness, but remain attached to the tree.

This acorn is in the process of turning brown.


The cap on this acorn is unexpectedly revealing, allowing us to see the acorn itself.


In this photo, we see a ripening nut with a cap that hasn't lost its greenness.

All of these acorns were found in the leaf litter. These are big fruits, easy to spot, if you happen to be looking for them.
