The Platycodon ‘Sentimental Blue Balloon Flower’, Platycodon grandiflorum, is
a low growing perennial with blue, balloon like flowers that bloom in late May
until August. (The flowers should be deadheaded to increase bloom time.) The
blooms puff up before opening and have a wonderful green foliage. With a plant
spread of 8-12” and a height of 8”, it is one that should be in every
perennial garden.
