The densely spaced flowers completely cover the plant while in bloom for an intense burst of color. The Platycodon grandiflorus has dark green foliage.
The Balloon Flower is a fast-growing plant with a compact, mounded form. Feature this plant in beds, mass plantings, or borders. The blue blooms look amazing against the hardscape of a rock garden. The easy-to-grow Pop Star™ Blue Balloon Flower also makes an excellent container plant, so you can display this stunner on a table or in a window box and admire the flowers up close. Grow this plant as a perennial in zones 3 through 9.
Pop Star™ Blue Balloon Flower Care
