Tree of the Week: White Oak (Quercus alba)

Our tree of the week is a white oak (Quercus alba) growing near Rotary and Cline dormitories. Continuing our project, Acorn Watch 2022, we are interested in its large clusters of acorns, but for a moment, study the cute little rain lily flowers, found in the above photograph, to the right of the flaky, white bark. Rain lilies are popping up in the arboretum and alongside the roads of Caddo parish. For the past week, we have had wet weather, and the rain lilies, true to their name, are responding to all of the moisture!

Our tree of the week is approximately 16 years old. It volunteered in the arboretum and was shortly thereafter moved to this sunny location, next to the sidewalk that runs from Cline Hall to the Student Union Building. The red bricks of Rotary Hall are pictured in the background.


This photograph shows the current state of our sunny slope near the dormitories. The hill gradually slopes down to the main drainage channel of the arboretum. The Fitness Center is also located at the bottom of this hill. Hopefully, within the next decade, this spot won't be so sunny.

The white oak is loving its location at the top of the hill. Do you see all of the acorns?!? This tree appears to be thriving. Maybe it also likes the extra water provided by the arboretum irrigation system.

The nut, the green meaty part of these immature acorns, has yet to expand outward. Right now they're snugly nestled down in their caps. We do not expect these acorns to ripen any time soon. In 2018, we had a photoshoot with acorns from our two on-site natives; those acorns weren't dropping until November. You can read that post here.
