The larkspur is an annual member of the buttercup family that hails from the Mediterranean. The upright plant reaches an average height of between 2 and 3 feet, producing deeply saturated, silky flowers in an array of colors, including purple, blue and white.

The common snapdragon (Antirrhinum majus) is a short-lived perennial or annual native to North Africa, Spain and parts of the Mediterranean. The plant ranges in size, with tall varieties growing up to 3 feet tall and dwarf varieties reaching 1 foot or less. The common snapdragon boasts rows of soft, fluffy flowers in almost every color except true blue. The flowers are highly attractive to hummingbirds. The flower works well in temperate regions, though it may also be grown in tropical zones. Snapdragons do best in full sunlight in USDA zones 4 to 11, ideally in a well-draining soil that's loaded with organic matter. Water snapdragons frequently, especially when you first plant them.
