Product Description
Platycodon 'Astra Double Blue'
Common Name: Balloon Flower.
Zones 3 to 8.
Full sun to part shade.
Plants reach 8 to 10 inches tall and 6 to 8 inches wide.
Growth rate: Moderate, herbaceous clump-forming perennial.
Blossoms swell into balloon-like buds before they burst open into fully double, bell-shaped flowers. Exceptional branching and thick flower petals make for long-lasting periwinkle blue blossoms. Its compact, uniform habit makes 'Astra Double Blue' a good selection for cut flowers, containers, or the garden. Deadheading generally prolongs the bloom period.
