Did you Know?
The fascinating and bizarre Unicorn Plant (Proboscidea louisianica) of the plants that start with U, has a shocking seed pod that turns into a weapon! When the green, horn-shaped fruit dries out on the stem, it splits open into two long, curved woody claws that look like a devil’s horn. These hooks are structurally engineered to catch onto the ankles of passing deer or livestock, forcing the animals to carry the pod for miles while it scatters seeds across the landscape!
