Platycodon Grandiflorum. This fun addition to the perennial garden produces purple-blue or white flowers that bloom from June to August. The flower buds look like miniature balloons, hence the common name, and the buds open to display star shaped flowers. Deadheading will encourage the plants to set more flowers.
Native to East Asia, the plants grow 1-3' tall and 1-2' wide. They grow best in full to part sun in well-drained soil. In the Spring, new growth is late to emerge, be patient! Once established, plants are deer resistant.
Plants are easy to start from seed. Start inside 10-12 weeks before the last frost date or sow directly outside when danger of frost has passed. Press the seeds gently into the growing medium but do not cover as they need light to germinate. Seeds should germinate in 21-30 days at 65-70 degrees. Plant 1.5 to 2' apart in the garden.
USDA Zones 3-8.
Heirloom seeds are collected, cleaned and packaged by hand at Mount Vernon.
