You will need plenty of space for this beauty, which can spread wider than it is tall, maturing at over 100 feet. Often dominant in the canopy, the State Tree of Maryland supports 80 birds and mammals and up to 534 Lepidoptera species. How fitting that the largest recorded US specimen lived on Maryland’s Eastern Shore. At nearly 500 years old, the majestic Wye Oak fell in 2002.
