Balloon Flower 'Sentimental Blue' (Platycodon grandiflorus) is a compact, long-lived perennial that starts with plump, balloon-like buds that open into star-shaped, rich blue blooms in summer. You will love how the flowers float above neat, leafy stems and keep coming when you remove spent blooms.

Give it full sun for the best flowering, but it will also perform well in part shade, especially where summers are hot. Plant it in light, fertile, well-drained soil that stays evenly moist, and avoid heavy, waterlogged sites. Once established, it is fairly easy-care, but it prefers not to be moved, so choose its spot carefully.

At maturity this dwarf selection forms tidy mounds about 6 to 8 inches tall, making it a natural fit for edging, the front of borders, rock gardens, and mixed containers. Combine it with other compact perennials and fine-textured grasses for a clean, modern look, or tuck it into cottage-style plantings for a pop of true blue.

Cut stems back in fall after the foliage declines. In spring, be patient: new shoots can emerge late, so mark the planting area to avoid accidental digging. With a little consistency in watering and a stable spot, this plant will reward you with dependable color year after year.
