In Mark 11, what did Jesus curse when he found nothing on it but leaves?

Answer: A fig tree

Jesus said, "May no one ever eat of your fruit again." The next morning the disciples saw the fig tree withered from its roots.

“Seeing in the distance a fig tree in leaf, He went to see if there was any fruit on it. But when He reached it, He found nothing on it except leaves, since it was not the season for figs.”— Mark 11:13 (BSB)
