Balloon Flower Roots (3 Bareroots) – Platycodon Grandiflorus, Doraji, Chinese Bellflower, Zones 4–9

The Beloved Balloon Flower — Ornamental, Culinary & Medicinal Heritage from East Asia

Balloon Flower (Platycodon grandiflorus), known as Doraji in Korea, is one of East Asia’s most cherished plants — celebrated for its inflatable, balloon-shaped buds that burst open into elegant star-shaped violet-blue flowers, and for its deep tuberous roots prized in Korean cuisine and traditional medicine. Native to Japan, China, Korea, and the Russian Far East, it has been cultivated for over 2,000 years as both a culinary ingredient and a revered herbal remedy. Hardy in Zones 4–9, each order includes 3 bareroots ready to plant.

Highlights

• 3 bareroots per order — Zones 4–9, full sun to afternoon shade
• Distinctive balloon buds — pop when squeezed; star-shaped flowers in violet-blue
• Grows 1–2 ft tall × about 1 ft wide; excellent in borders and rock gardens
• Hardy perennial; drought-tolerant once established
• Edible and medicinal roots; edible leaves (salads, garnish)

In the Kitchen

In Korea, Doraji root is candied, pickled in brine, or used in traditional side dishes like doraji-muchim and doraji namul — common in Korean homes and restaurants. Dried roots are available in Asian grocery stores and can be added to soups, stir-fries, and teas. The root is brewed with jujubes (red dates) to balance its natural bitterness. In Japan, young leaves are used in salads.

Medicinal Uses

For over 2,000 years, Balloon Flower root has been used in traditional East Asian medicine to address respiratory and digestive disorders, reduce inflammation, fight fatigue, and support liver and heart health. Modern studies suggest the root may inhibit the growth of certain cancer cells. Often compared favorably to ginseng in Korean tradition.
