Tree of the Week: Durand Oak (Quercus sinuata)

Continuing our study of the arboretum's acorn production, we have photos below of the Durand oak and its immature acorns. Out there in the bright sunshine, our Durand oak is labeled Quercus durandii, but another widely used binomial is Quercus sinuata.

Our lone Durand oak (Quercus durandii syn. Q. sinuata) is approximately 25 years old. You can read about its acquisition on an older blog post found here.


This week in July, you can find immature acorns on the branches. This isn't the first time that we have seen fruits on this tree. In June of 2019, we posted photos of developing acorns; however, we have yet to examine mature fruits.

 

There are more than a handful of immature fruits that are easily observable from the ground.

And, if the sweltering heat and blinding sunrays haven't convinced you that summer has arrived in northwest Louisiana, here we have another sign of the season―a cicada exoskeleton was found firmly attached to our Durand oak.
