Antirrhinum majus
Antirrhinum majus (common snapdragon; often - especially in horticulture - simply "snapdragon") is a species of flowering plant belonging to the genus Antirrhinum. It is native to the Mediterranean region, from Morocco and Portugal north to southern France, and east to Turkey and Syria. The common name "snapdragon", originates from the flowers' reaction to having their throats squeezed, which causes the "mouth" of the flower to snap open like a dragon's mouth.
Description
It is an herbaceous perennial plant, growing to 0.5–1 m tall, rarely up to 2 m. The leaves are spirally arranged, broadly lanceolate, 1–7 cm long and 2-2.5 cm broad. The flowers are produced on a tall spike, each flower is 3.5-4.5 cm long, zygomorphic, with two 'lips' closing the corolla tube; wild plants have pink to purple flowers, often with yellow lips. The fruit is an ovoid capsule 10–14 mm diameter, containing numerous small seeds. The plants are pollinated by bumblebees, and the flowers close over the insects when they enter and deposit pollen on their bodies.
