Bright snapdragon flowers bloom profusely throughout cool weather in intensely saturated colors (almost every hue) and are real standouts in either the spring or fall garden. The flowers start blooming at the bottom of the stalk and work their way up, making for a long period of bloom. Although snapdragons tend to stop blooming in heat of mid-summer, if you keep them watered, they will perk up and carry your garden through the fall. The flowers resemble opening mouths when they are pressed on their sides. The openings of the flowers are snapped tightly shut and require more pressure to open than a honeybee can provide, so snapdragons rely on heavier bumblebees for their pollination. The Liberty series grows 18-22″ tall whereas the Snapshot dwarf snapdragons only grow 6-10″ tall.
