Noteworthy Characteristics

This balloon flower cultivar is a dwarf selection that typically grows to only 6-12" tall. Features unique, puffy flower buds shaped like hot air balloons which open into 3" diameter, single, blue, upward-facing, bell-shaped flowers with five pointed lobes. Oval, dentate leaves to 3" long. Blooms most of the summer.


No serious disease or insect problems. Emerges very late in the spring, so gardeners must be careful not to damage the crowns in early cultivation.

Garden Uses

Mixes well with other perennials and provides good color and long summer bloom to the border front or rock garden.
