Snapdragons are tall, charming plants, and flower in a range of bright colors. In Spain, where snapdragons grow wild, these flower colors show a remarkable pattern: When driving up a road from Barcelona to the Pyrenees, snapdragons of the species Antirrhinum majus bloom in magenta at the beginning of the road, before a population of yellow flowering snapdragons takes over—separated by just a two-kilometer-long stretch in which flower colors mix. Such hybrid zones of snapdragons are quite infrequent; only a few others are known.
