About Blackjack oak
Blackjack oak is a native treasure that belongs in any wildlife-friendly yard. Birds and other animals depend on the acorns and shelter these trees provide. The leaves turn a wonderful russet color in fall, and the dark bark gives the tree its fitting name. Even in poor soil where other trees struggle, blackjack oak thrives and asks for very little in return.
Once established, this oak is wonderfully low-maintenance. It's tough and adaptable, preferring sunny spots where it can grow strong. Water it well during its first year while it gets settled, then let nature take over. You'll be rewarded with a long-lived native that improves your land and supports the wildlife around you. That's a gift that keeps giving.
