Pollination Information for Shumard Oak Tree (Quercus shumardii)

The Shumard Oak tree is monoecious, which means it has separate male and female flowers on the same tree. The male flowers are small and yellowish-green, and produce large amounts of pollen. The female flowers, which are also yellowish-green but larger than the male flowers, are located on the same tree.

The pollination occurs through wind, meaning the pollen is carried by the wind from the male flowers to the female flowers on the same tree, and sometimes, to the female flowers on other trees. This pollination method is called "anemophily".

The Shumard Oak tree blooms from April to May and sometimes into June, usually after the leaves have emerged. The female flowers develop into acorns once fertilized by the male flowers. The Shumard Oak tree can produce a large number of acorns each year.

Various insects such as bees, wasps and beetles sometimes visit Shumard Oak flowers but they are not significant pollinators.
