2022 Acorn Watch: Post Oak (Quercus stellata)

 

Today is the first day of fall, and we have good and bad news about post oak acorns.

 
Back in June, we were happy to see nice clusters of acorns developing on the small post oak (Quercus stellata) growing near Cline Hall. In the above photograph, we see five acorns along the branch. These were easy to see from the ground. You can find more photos on the blog post found here.

Unfortunately, on the first day of autumn, the acorns, at least the ones on the lower branches, are hard to find, and they do not appear to be on schedule for proper development.

 

This is one of the few acorns that can be found while standing on the ground. We see a cap with only a  glimpse of the green fruit. Compare this acorn with the fruits in the below picture.

These three acorns were found on a different tree―an on-site native post oak growing on the outskirts of campus, near Centenary Boulevard. The green fruit is rounded and signficantly protruding from the cap. So, the good news is that the elderly population of post oaks will provide acorns for a germination project.
