Spotted bellflower is a herbaceous perennial native to Japan and Siberia where it grows in lowlands on disturbed soil such as roadsides and fields. The light green leaves are triangular and serrated. They form an attractive mound which sends up stems of large drooping bells from June to July. The flowers are white, rose, pink, or violet and have red spots and hairs inside. Although many bellflowers are well behaved garden plants, spotted bellflower spreads by stolons and can be invasive. Its vigorous nature can be forgiven, however, because it is one of the few bellflowers that grow well in USDA zone 7 and warmer. Good container plant and cut flower.
