Globe-shaped flower buds that resemble chubby balloons appear in mid to late summer, adding a fine blend of colors to the seasonal landscape. As the buds open, the shallow, bell-shaped blooms emerge in shades of blue, pink and white—a stunning combination for spring. Excellent garden performers, Balloon Flowers will thrive practically anywhere they are planted. From rock gardens to border beds, they grow up to 24" tall with a spread of 8-12". Very easy to grow and maintain, they need only well-drained, fertile soil to be happy. Once established, Balloon Flower should be left alone as they do not like to be disturbed. Hardy in Zones 3-9.
