  • Question

    This tree fell during a recent storm. Just going off the bark, I would have identified this tree as either Quercus rubra, or Q. coccinea (parallel ridge pattern extends to nearly the base as opposed to dark blocky bark). However, the buds (at the crown) are greater than 7mm, angled, and covered in down which would lead me to identify as Quercus velutina. Could this individual potentially be a hybrid? Any recommendations to identifying when buds are not within reach in winter? SE CT. Upland site

    Answer

    Dear eehrlich, The tree looks to be Quercus velutina. The bark of this tree, compared with Quercus rubra, is not always sharply distinct. Though many trees can be distinguished by bark alone, I have seen individuals that required additional characteristics to determine the species. One useful characteristic for Quercus velutina is that underneath the outer bark the color is distinctly yellow (or sometimes orange-yellow). Quercus rubra and other species are not as bright underneath the outer bark (viewed by using a blade to create a hole in the outer bark). This can help when winter buds are not available.
