Fun, weird, helpful, or little known fact
Distinguishable from its close relative, Geranium viscosissimum, by the sticky, red-ball-tipped (“glandular”) hairs on the stem below its flower, as opposed to the yellow-tipped hairs on G. viscosissimum.
Geraniums have evolved a wonderful method for successfully planting their own seeds. Its seeds are attached to a reproductive part of the flower, the style, that coils like a spring. Once it falls to the ground, it coils and uncoils in response to changes in atmospheric pressure, thereby drilling itself and its seeds into the ground.
