I said New Jersey's official state fruit is the blueberry. The blueberry is the state fruit. I already told you how I feel about a Jersey tomato. The state made it official in 2004 — and kids from Brick made it happenNew Jersey designated the blueberry its official state fruit in 2004, and the push behind it didn't come from Trenton. It came from a fourth-grade class at Veterans Memorial Elementary School in Brick, who realized during a New Jersey history lesson that the state had never actually named an official fruit.
