Blackjack leaves have less distinct lobes and generally have only 3 of them.<br /><br />That leaf looks more like a Post Oak leaf, which is also a smallish oak and native to Kentucky. <br /><br />If you want to know if it is a blackjack oak, here's a suggestion. Blackjacks are a member of the red oak... one of only a few reds that have rounded lobes. Red oak acorns typically take 18-24 months to come to maturity before falling from the tree. They are also quite high in tannins when they first fall, making them very bitter in flavor. <br /><br />Post oaks are in the white oak family. Their acorns mature in the first summer.<br /><br />Take a freshly fallen nut and taste the meat inside. If it is bitter, it is a red oak and potentially a blackjack. If it isn't bitter, you can be sure it's a white oak, such as a post oak.drhenderhttps://www.blogger.com/profile/13886783696974833376noreply@blogger.com
