Platycodon grandiflorus 'Sentimental Blue'

Balloon Flower

Platycodon grandiflorus 'Sentimental Blue' is a dwarf selection that typically grows to only 6-12" tall. Features unique, puffy flower buds shaped like hot air balloons which open into 3" diameter, single, blue, upward-facing, bell-shaped flowers with five pointed lobes. Emerges very late in the spring and blooms most of the summer. Prolific bloomer!

Balloon Flower Growing and Maintenance Tips:

Easily grown in average, medium, well-drained soil in full sun to part shade. Division and transplanting are possible but tricky because of the stringy root system, and it may be best to leave the plants undisturbed.
