Don’t worry if you are a newbie in gardening! My list includes easy-to-grow purple perennial flowers. Plus, they will attract pollinators, like bees and butterflies, as well as other helpful insects to your garden.
African Lily

African Lily, or Agapanthus, is a show-stopper with its huge, globe-shaped clusters of blue or purple flowers. I love to grow them in containers or along borders for a bold look.
These beauties thrive in soil that drains well and receives full light. You may also put African lilies in containers to bring them indoors during cold weather.

One of my favorite late-season flowers is asters. When other blossoms start to fade, these purple flowers come alive. They draw butterflies and bees like crazy!
Full sun and wet, well-drained soil are ideal growing conditions for asters. To create a lovely cottage garden effect, I suggest planting them in clusters.
Bellflower

Bellflowers, also known as Campanula, are charming plants with exquisite purple, blue, and white bell-shaped flowers. I frequently use them to bridge the spaces left by larger perennials.
