Plants with purple blooms include verbena, lavender, clematis, bellflower and dwarf iris. These plants are popular for their easy care and are perennial in the right climates.
The bonariensis species and the Imagination cultivar of verbena feature clusters of small blooms in bright shades of magenta and violet. The plants grow perennially in zones nine to 11 and annually elsewhere. The plant grows to 18 inches and blooms throughout the summer in sunny locations with moist, well-drained soil.
Lavender, genus Lavandula, is perennial in zones five to 10. Gardeners can grow the plant in full sun for their small light-purple blossoms and pleasant scent or harvest them for their edible leaves and flowers. The plant features silvery foliage and grows from 1 to 4 feet tall.
Jackmanii and Arabella cultivars of clematis provide purple, blue and mauve blossoms on vines that can grow up to 30 feet. The plants grow best in sunny, sheltered areas in zones three through nine.

The dark purple blossoms of the J.S. Dijit dwarf purple iris, iris reticulata, emerge from late winter to early spring. The small, 2-to-4-inch plant prefers full sun and grows in zones four through nine.
