Balloon Flower Growing and Maintenance Tips

Grows best in an average to moist, well-drained soil, in full sun to partial shade. Not easily transplanted once established. It is late to emerge in spring, so it is important to mark the crown areas to avoid damage during early cultivation. Remove spent flowers to prolong bloom time or prune back after flowering to maintain shape.
