Shumard’s Oak

Shumard’s Oak 

Quercus shumardii Buckley 


 Shumard’s oak (beech family, Fagaceae) typically range between 50 and 90 feet. Their bark is thick and smooth with a gray tint. As the tree develops and grows it becomes more wrinkled and a darker gray shade¹.  The tree has great urban adaptability, is drought tolerant and fast growing. It prefers to grow in well-drained soil¹. The 6 to 8inch leaves are arranged in an alternate assortment, with a simple complexity and pinnate venation². They are 5-9 lobed with sinuses about three-fourths to the midrib, bristle tipped, and dark green on top and paler below.  Male and female flowers are on the same tree but have different characteristics.  Male flowers are represented by dangling catkins while the female flowers are smaller and can be found close to the stem³. The acorns mature in about two years and grow to be about 0.75 to 1.25 inch with a saucer shaped cap covering one-quarter of the nut².  Acorns must overwinter on the ground before germinating.
