Snapdragon is a garden flower native to southwestern Europe and widely grown in the United States. The usual flowers have two lips that open like a dragon’s mouth when pressed, giving snapdragon its name. Garden varieties include short edging plants and cut-flower types reaching 3 ft (0.9 m), with solid or bicolored blooms.
Angelonia has smaller flowers with an open center. A typical snapdragon flower has lips that meet until they are pushed apart.
