A garden design that includes purple perennial plants can create one of the most striking landscapes. Perennials come in many shades of purple, but I also use various types of Lilacs (as shown here). 'Miss Kim' is a smaller one while 'Bloomerang' is a repeat bloomer. Take a look at some of my favorite purple flowering plants.
Liatris spicata also known as Blazing Star is a beautiful purple perennial. Its grass like foliage and tall blooming spikes attract butterflies, birds and bees. Liatris is a great cut flower and is deer resistant. Plant with Bee Balm and Black Eyed Susan’s for a vibrant garden. (Liatris spicata)
"Purple Heart" plant. So easy to grow! Comes back year after year. You can easily divide this plant by pinching off a clipping where it forms a "V" and transplant in rich soil. Makes a beautiful border!
