55 Purple Perennial Flowers That Are Easy to Grow

Purple Perennials

Flowering purple perennial plants add wonderful shades of lilac, violet, blue, and lavender to your garden. Purple perennial flowers vary in size from beautiful large blooms on a phlox to delicate violet petals on irises. Planting purple flowers is also a great way of attracting pollinating insects as the various purple shades attract bees and butterflies.

Some types of purple perennials are low-growing creeping plants that help to provide good ground cover. 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.

Purple, the color of royalty, adds a touch of class to your garden. Whatever your landscaping needs, there are purple perennial flowers to meet them.

In this article, you will find out about the qualities, features, and characteristics of the most popular purple flowering perennials.

What Are Perennial Plants?

Perennial plants are defined as plants that live more than two years, unlike annual plants that live one growing season, and then die. Flowering perennials grow and flower during spring and summer, die back during the cold season, and then grow back in spring.

Some flowering perennial plants are short-lived and last only a few years, whereas other perennials are long-lived.

Do Perennial Plants Come Back Year After Year?

Not all perennials come back year after year. Some perennial plants are not hardy and they don’t survive the harsh cold winter. They only grow one year and as such can be defined as annuals. They are also called tender perennials.

Some perennial plants can come back year after year. These are hardy perennials and they tolerate the harsh cold winter. They will keep coming back after a cold winter.

Some short lived perennial plants only bloom once in the second year and then die. In this case they will need to be replaced after 2-3 years. Other longer lived perennial plants lose their vibrant growth after several years and will need to be replaced from time to time.

Purple Perennial Flowers (With Pictures and Names)

Iris (Iris spp.)

Algerian Iris (Iris unguicularis) 

The iris is an extremely popular and common flower. There are many cultivars of iris with beautiful purple flowers

Iris is a bulbous perennial flowering plant that has some stunning purple cultivars. If you are looking for bright blue or purple flowering irises, then choose the ‘winter iris’ (Iris histrioides) or the ‘netted iris’ (Iris reticulata). However, other types of irises have been cultivated to flower in various shades of purple.

If you want to decorate your garden with incredibly beautiful purple flowers, then irises are one of the first bloomers in spring. Their delicate deep purple spring flowers appear near the end of January or start of February.

Purple flowering irises, as with other types of iris, are hardy perennial plants that survive winter. To make sure irises thrive, plant them where they get full sun at least a half day and in well-drained soil.

Irises are one of the best plants to bring color to mixed flower beds. Being relatively tall perennial flowers, it’s best to plant Iris flowers at the back of a flower bed, or you can plant them in a row as a border to define a landscaped area.
