Pop Star™ Blue Balloon Flower

Pop Star™ Blue is the blue color variety in the compact Pop Star™ balloon-flower series. Its rounded buds open into blue, star-shaped summer flowers above a tidy, green-foliaged mound. ## Bloom and scale The [Florensis series listing](https://www.florensis.com/en/products/bedding-plants/annuals/platycodon-grandiflorus/platycodon-grandiflorus-pop-star) identifies Blue as one of the named color varieties in Pop Star™. A [nursery product profile](https://www.tree-land.com/products/pop-star-blue-balloon-flower) reports a mature size of about 8–12 inches tall by 10–14 inches wide, USDA zones 3–8, and full sun to partial shade. These compact proportions suit border fronts, small gardens, and containers where the flowers can be seen up close. ## Growing conditions Balloon flower grows best in full sun to partial shade and well-drained, slightly acidic soil, according to [North Carolina State Extension](https://plants.ces.ncsu.edu/plants/platycodon-grandiflorus/). The plant’s balloon-like buds open into five-pointed flowers, giving it interest before and during its summer display. ## Maintenance Water regularly while the plant establishes and avoid poorly drained soil. Remove spent flowers to prolong bloom, as North Carolina State Extension recommends. Balloon flower develops a fleshy root system and is difficult to divide or transplant, so choose a lasting planting spot.
