We love this one for its unique, puffy flower buds shaped like hot air balloons that open into blue, upward-facing, bell-shaped flowers. This cultivar named Sentimental Blue is a dwarf selection that typically grows to only 12" tall. Blooms most of the summer, mixes well with other perennials and provides good color and long summer bloom to the border front or rock garden.
Prefers a well-drained soil in full sun. Not fussy about soil but doesn’t like “wet feet”. Tough, hardy and easy to grow.
Grows to 10-12” high and 24” wide. Dormant in winter.
