Platycodon grandiflorus, or balloon flower, is a clump-forming perennial named because its flower buds puff up like balloons before bursting open into outward-to-upward-facing, bell-shaped blue flowers with five pointed lobes. Plants are native to the slopes and meadows in China, Japan, Korea and Siberia. Purple-blue flowers (to 2-3” across) bloom throughout summer, singly or in small clusters, atop stems typically growing 2 to 3 feet tall.
