Orange jewelweed
Impatiens capensis
An annual, juicy herb with orange, spotted flowers. Ripe seed pods burst open when touched and shoot the seeds away, hence the names touch-me-not and jewelweed. The sap contains saponins and naphthoquinones; one study found it can prevent a poison ivy rash after short exposure, though washing with soap works at least as well.
