Rapid plant movement Information & Rapid plant movement Links at HealthHaven.com

The Venus Flytrap is one of a very small group of plants that are capable of rapid movement.

Rapid plant movement encompasses movement in plant structures occurring over a very short period of time, usually under one second. For example, the Venus Flytrap closes its trap in about 100 milliseconds.^[1] The Dogwood Bunchberry's flower opens its petals and fires pollen in less than 0.5 milliseconds. The record is currently held by the White Mulberry tree, with flower movement taking 25 μs, moving petals to velocities in excess of half the speed of sound — near the theoretical physical limits for movements in plants.^[2]

These rapid plant movements differ from the more common, but much slower "growth-movements" of plants, called tropisms.

Charles Darwin in 1880 published his last work before his death, The Power of Movement in Plants.

[edit] Plants that spread seeds or pollen by rapid movement

Squirting cucumber (Ecballium agreste)
Impatiens (Impatiens x)
Sandbox Tree
Triggerplant (All Stylidium species)

Pilobolus (Pilobolus x)
Some Fabaceae have beans that twist as they dry out, putting tension on the seam, which at some point will split suddenly and violently, spraying the seeds metres from the maternal plant.^[3]^[4]
