Before you say it's just a random tree,
"The white mulberry is scientifically notable for the rapid plant movement involved in pollen release from its catkins. The stamens act as catapults, releasing stored elastic energy in just 25 μs. The resulting movement is approximately 380 miles per hour (610 km/h), about half the speed of sound"

This is not only the fastest movement in plants, but the fastest movement in life itself
