Platycodon Seed Germination How to Sow Platycodon:
  • Best sown indoors at 65-75° with germination occurring in 10-15 days
  • Seeds can be sown indoors in January for flowering in June and July of the same year
  • Seeds can be sown outdoors in spring or summer, up to two months before first frost
  • Always, sow with NO cover as light aids in germination
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Platycodon:
Transplanting: Transplant when there are at least two sets of true leaves

Spacing: Plant out at 12-18 inches apart in full sun or light shade in a rich, moist, well-drained soil. Keep well watered

Temperature: Grow on at 60-65° days/55-60° nights

Additional Care: Pinch young plants to increase branching and flower production and deadhead to prolong the flower display. Plants are difficult to divide due to their long tap roots, but division may be accomplished by detaching rooted basal shoots in early summer. They are slow to emerge in the spring, so do not rashly cull the rootstocks before they have yet to begin growing for the season. Fertilize monthly

Appearance and Use:

A perennial for borders, beds, rock gardens, and for fresh cut flower use. Plants are compact and clump-forming from 2 feet tall to 12 inches wide. The showy balloon-like buds swell to burst open as 2-3 inch, bowl-shaped flowers with pointed petals. The buds and flowers are colored pink, blue, or white and appear in mid-summer. Foliage is bluish green, ovate to 2 inches long, and the margins are toothed
