Go native with false indigo, a prairie plant that’s low maintenance and gorgeous. Pretty blue-purple flower spikes appear in late spring and make a great addition to a garden-fresh bouquet. Leaves have a blue-green tone that looks stunning in a vase—harvest stems all season long. Dried seedpods make a nice addition to fall arrangements. This is a tap-rooted perennial, which means it’s not easy to move once established. Plant it where you know it can stay put. False indigo offers different flower colors, including blends of blue, yellow, brown and white. The variety shown is ‘Blueberry Sundae.’ False indigo are deer-resistant plants that grow 4 feet tall by 3 to 4 feet wide. Hardy in Zones 3-9. Good vase companions for false indigo: bearded iris, peony, clustered bellflower, purple coneflower and echibeckia.
