False Indigo blends beautifully with pastel, late spring bloomers, like peonies, as well as with shocking colors. Spiky plants, such as iris, salvia, and tall alliums, complement both the color and the texture of Baptisia. The blue blossoms really bring out the chartreuse of Lady’s Mantle. Since it is a large plant and it only blooms once, be sure to put your false indigo plant somewhere in your garden where its foliage will continue to offer interest. Snuggling it between other plants will prevent the branches from falling open under the weight of the flowers and seed pods. This plant is also a good addition to wildlife gardens, as it serves as host to several species of butterflies.
