Overview
Whimsical flowers whose 'jaws' open and close when squeezed, snapdragons have delighted children and gardeners for centuries. Available in virtually every color except blue, they bloom abundantly in cool weather and are outstanding cut flowers. While technically a short-lived perennial, they are usually grown as annuals and self-seed readily in gardens they enjoy.
