Platycodon Grandiflorus is a very useful perennial in beds and borders and a favorite of young and old alike. Balloon Flowers establish readily from flower seed, and once they are established in the garden, they are a very hardy perennial that can withstand periods of drought. Balloon Flower Platycodon has mid to dark green foliage which emerges in late spring. Balloon-like buds swell and burst into large, star-shaped, rose-colored flowers. They are great for borders of your garden or even in containers. Balloon Flower plants are rarely bothered by disease or insect problems making it virtually a maintenance-free perennial.
