This strain  has long strong stems and mid blue flowers and was specifically bred for the flower trade. It forms a compact mound of deep green foliage from which arise inflated buds that open into star-shaped single blue blossoms.  The plants come up quite late in the spring, and continue blooming from early to late summer. They make a good cut flower. Deadhead them regularly to maintain the flower production, and prune back after flowering to maintain the plant’s shape.

The genus Platycodon belongs to the Campanulaceae family and contains only one member: Platycodon grandiflorus. It is  native to Eastern Asia, The plant is commonly known as Balloon Flower. This name is based on the unopened flower buds which look like little balloons.

They like full sun and will tolerate partial shade, and grow in average to moist well drained soil.

They do not like to be moved once established . As they come up very late in spring it is a good idea to mark where their crown is to avoid mistakenly pulling them out.
