Attract Butterflies with 7 Purple Perennial Flowers Attract Butterflies with 7 Purple Perennial Flowers

Butterflies love the sweet nectar of purple perennials that compliment any perennial garden. These purple perennials are a must-have when it comes to attracting butterflies to your garden.

TIP: Our expert gardening advisor, Susan Patterson adds, "Always plant your butterfly garden in full sun, and remember to provide a fresh source of water for the butterflies. Add a layer of mulch to your perennial flowerbed to help with water retention. Cut perennials in the fall and cover with a light layer of mulch for winter protection."
