The "Generator Oak" this tree holds our 2012 height growth record. We were able to grow a 18" seedling to a 10 Foot Tall Sapling in only one growing season!

Toxey discovered this hybrid between Shumard oak and willow oak in a planting of willow oaks when he noticed it was much bigger than the rest of the surrounding trees. Upon closer inspection, the little leaves had jagged margins kinda like a sawtooth or chinkapin oak.  Fast forward several years- the tree’s super growth rate hasn’t changed and routinely generates WAY more acorns every year than the surrounding oaks…hence its nickname “the Generator.” It also is highly prized by the wildlife.  One interesting thing we noticed with this hybrid red is that squirrels dine on the acorns immediately after falling, instead of hauling them off to a cache. This is common with the white oak group, but squirrels normally reserve reds for later after losing some bitterness. The acorns are bigger than a willow oak’s and smaller than a Shumard oak’s, making them just about perfect for all of our favorite wildlife species.  In a hurry???,  the rapid mast seedlings from the Generator oak grow VERY fast and will routinely hit the 6-8 foot mark their first year when paired with your best dirt, a tree tube and proper care.   Like some of the other fast growing reds such as Nuttall and Shumard oak, 6-8 years to acorns isn’t unheard of if you do it right.
