Tall Purple Perennials. So enjoy purple perennials in your garden. Technically they're biennials, meaning they'll live two years and die.
Other flowering perennials are larger shrubs or bushes that have stunning purple, mauve, and lilac clusters of flowers. Some tall perennials have purple flowers that grow at the end of long stems. In particular red flowers symbolize love, yellow ones symbolize joy, white blossoms mean purity, and purple ones indicate nobility and elegance.
Spanning the range from violet to maroon, to blue purple, to pale lavender, there are plants with purple flowers for all tastes from mild to wild.
For plants that come back year after year with little help from you, choose perennials.
However, I'd like to have some tall shade-loving perennials that grow above the ground covers to add some height and texture. Count on this attention getter for color all season in any landscape. Coralbells' tiny perennial flowers, borne on stalks above the leaves, appear in late spring.
