A fun perennial, Pop Star Balloon Flower, Platycodon, features flower buds that swell into huge plump balloon-like orbs then pop open to reveal huge star-shaped violet blue, star-shaped blossoms. It has a very compact habit, growing only 6-8″ tall and 10-12″ wide. Long blooming, you can expect to see its beautiful blossoms throughout summer. Full Sun
