Dwarf Dogwood (Cornus canadensis) is believed to be the fastest blooming flower in the world, blooming in just 0.5 milliseconds, faster than a bullet traveling the length of a rifle barrel. The four petals have antenna-like structures at the tips that hold them together tightly until a heavy insect like a bubblebee triggers them to open explosively. The rapid petal release can fling pollen out up to 2.5 cm away, which is a distance about 10 times the height of the flower (from Edwards, J., et al. Botany: A record-breaking pollen catapult. Nature 435, 164. May 12, 2005). Bunchberry can be found throughout the lower-elevation forests of Mount Rainier. NPS/Emily Brouwer Photo taken June 10, 2014.
