Platycodon grandiflorus 'Astra Semi-Double Blue'

Balloon Flower

Platycodon grandiflorus, commonly called balloon flower, is a clump-forming perennial that is so named because its flower buds puff up like balloons before bursting open into outward-to-upward-facing, bell-shaped flowers with five pointed lobes. 

Platycodon ‘Astra Semi-Double Blue’ is a compact cultivar that produces blue semi-double flowers singly or in small clusters atop stems throughout the summer. Excellent branching.

Balloon Flower Growing and Maintenance Tips:

Best grown in light, medium moisture, organically rich, well-drained soil in full sun to part shade. Avoid wet or poorly-drained soils. Plants are easily grown from seed. Division and transplanting are possible but tricky because of the fragile, fleshy root systems of these plants, and it is probably best to leave plants undisturbed once established. Deadheading spent flowers generally prolongs the bloom period. Leave old plant stems in place throughout winter until new growth first appears to help mark plant locations.
