Balloon Flowers resemble members of the bell flower family. However, they contain larger petals that balloon into a double star pattern. Elegant indigo clusters of blossoms rise from the tops of vigorous green stems, making this a splendor to behold among the flowers. They flourish in full sun or part shade, and prefer morning sun to the hot afternoon sun. Stems emerge in late spring with flowers appearing in early summer and extend through the season especially when some routine deadheading occurs. They prefer well drained, loamy soil, and will suffer in waterlogged areas. Known to be self sowing, but not an aggressive spreader, Balloon flowers are hardy (Zone 3), with low water needs, as well as being deer resistant. Easy to maintain perennial, a top choice! Plus the bees love them!
