Description

Large blue buds swell like little balloons, then burst open into star-shaped flowers that light up the summer garden. These plants reach about 20 inches tall and bloom when many other flowers are fading, bringing fresh color deep into the season. Hardy in zones 3–9, they also carry a long culinary tradition, as the roots are commonly used in Asian cooking. A lively and memorable perennial with both beauty and usefulness. Easy to grow!

Growing Guide

When to Grow

Sow seeds indoors 6 to 8 weeks before your last frost, or direct sow after the last frost has passed; balloon flower seed can also be direct sown in fall or in spring. Allow 110 to 120 days to maturity. Fuji Blue keeps setting tons of explosive little blooms late into the season, when many other flowers are spent.

How to Sow and Plant

  • Seeds germinate in 5-15 days.
  • Seeds can be direct sown in fall or spring. You can also start seeds indoors in early spring.
  • Cover seeds with a thin sprinkle of soil (light aids germination).
  • Lightly water.
  • Ideal germination temperature is 65-75 F.

How to Grow

  • Cold hardy perennial from USDA zones 4-9.
  • Prefers full sun and part shade.
  • Well-drained, slightly acidic soil is best.
  • Balloon flower will tolerate moderate dry spells but prefers consistent moisture.

PESTS/SPECIAL CONSIDERATIONS

Plants are insect and disease resistant and resistant to deer.

How to Save Seeds

  • Balloon flower is the only member of the genus platycodon, so seeds can be saved reliably without chance of cross-pollination.
  • The small seeds will readily shake from the pods.
