Platycodon grandiflorus (Balloon Flower) [25 Seeds]


Germination Information: Sow in pots, either indoors in late winter to late spring (in a bright spot at around 70°F) or outdoors from late spring to midsummer. Scatter the seeds evenly over the surface of moist growing medium and press them into the surface; do not bury them, and don’t let the growing medium dry out. Germination can be slow; look for some seedlings in 3 to 4 weeks, with additional sprouting possible thereafter. If you start the seeds early, they might flower the first year; otherwise, expect some flowers the second year, with increasing blooms thereafter.

Note that this information will not appear on the seed packet you receive.

Balloon flower (Platycodon grandiflorus) produces puffed-up buds that open into purple-blue flowers in mid- to late summer, with scattered rebloom in autumn. The rich green foliage turns yellow, sometimes shaded with maroon, in fall. Plants usually reach about 3 feet tall; if you wish to keep them somewhat shorter, try cutting the plants back by about half in late spring (in other words, if the plants are about 10 inches tall then, cut them back to about 5 inches above the ground). Full sun to partial shade. Perennial; Zones 3 or 4 to 8.

Harvested in late September 2022. At least 25 seeds.
