Platycodon grandiflorus, commonly called Balloon Flower, is a herbaceous perennial native to East Asia. It is known for its unique flower buds, which swell like balloons before opening into star-shaped blue, white, or pink flowers. The plant typically grows 1–2.5 feet (30–75 cm) tall with erect, unbranched stems and glossy green foliage. Blooming in summer, it adds vertical interest and reliable color to perennial borders and cottage gardens. Balloon Flower prefers full sun to partial shade and rich, well-drained soil. Suitable for USDA Hardiness Zones 3–8.
To germinate Platycodon grandiflorus seeds, sow them indoors 6–8 weeks before the last frost. Press seeds lightly into the surface of a moist seed-starting mix, as light aids germination. Maintain a temperature of 65–70°F (18–21°C) and provide bright, indirect light. Keep the soil evenly moist. Germination typically occurs in 14–21 days. Transplant seedlings when they have at least two sets of true leaves, and harden off before planting outdoors.
