Years ago when I learned that Jack-in-the-pulpit can change its sex from male to female and back again, I accepted this as the odd behavior of an odd flower. So I was stunned to learn that the striped maple (Acer pensylvanicum), a common understory tree in the Laurel Highlands, can change sex, too.
The striped maple’s current sex is evident in its flowers. These are male.
How does it change and when does it decide to do it? Adam Haritan describes the mystery in his 8-minute video at Learn Your Land.
p.s. They are called striped maples because their bark is striped.
