The silvery blue foliage forms and mound and out of the middle the flower spikes arrive. The dainty blooms draw a wide assortment of butterflies and bees to the garden. Even hummingbirds love the flowers. This plant grows best in USDA Zones 3 to 7. Plant in full sun for best flowering results.

  1. Lavender

Is any list of purple perennials complete without listing lavender? Gardeners have for centuries favored the classic cottage flower. The aromatic flowers make ideal soaps, potpourri, bath bombs, and cut dried bouquets. 

A low maintenance plant, lavender prefers  a sunny planting location. Place it along a walkway or by a deck where the aroma can truly be enjoyed during outdoor activities. 

New cultivars are constantly being developed. Nowadays, many can stand up to humidity and extreme cold. 

  1. Verbena 

Verbena might not be a towering showstopper, but its dainty size is appealing. It stands from six to 18 inches tall and produces ample flowers throughout the summer months.

The iris is a must-have in any garden. It grows well in USDA zones 3 to 9. After a few years, you can divide it and transplant a portion to other areas of the garden or give it away as a gift. Choose a planting site with at least six hours of sun per day to meet its needs.
