Growing Guide: Balloon Flower
Growing Tips
Plant Balloon Flower in full sun to part shade and well-drained soil. Water regularly while establishing, but avoid soggy conditions, as overly wet soil can lead to root rot. Once established, avoid disturbing the roots, as Balloon Flower does not like to be moved. Cut back stems after flowering to encourage tidy growth and potentially more blooms. For root harvest, dig in fall after the plants have had 1–2 years to establish.
