Orange jewelweed

Also known as common jewelweed, spotted jewelweed, spotted touch-me-not and orange balsam. The flowers are orange with a three-lobed corolla; one of the calyx lobes is colored similarly to the corolla and forms a hooked conical spur at the back of the flower. The seed pods are pendant and have projectile seeds that explode out of the pods when they are lightly touched, if ripe, which is where the name 'touch-me-not' comes from. The leaves appear to be silver or jeweled when held underwater, which is possibly the origin of the name jewelweed.
