Impatiens noli-tangere. Impulsive.
The plant Impatiens grows along woodland tracks where the ground is wet and beside woodland streams. The bright yellow, brown-spotted flowers, which look like hoods, are followed by narrow capsules, which at the slightest touch eject the seeds several metres away from the parent plant. Hence the name Touch-me-not.
The old fairy tale that follows resembles the plant. When the impulsive Little Red Riding hood walked in the forest alone, the Big Bad Wolf followed her, dressed in a hood to resemble her grandmother. Her mother told her not to go, in fact begged her to wait until her father returned. Once lured into her grandmother's cottage, Little Red nearly believed the imposter. Her father, the woodsman, hurled his axe just in time to prevent her death.
Proverb: It is easy to be wise after the event.
