Comments: Tall bellflower is a true biennial; seeds that germinate will grow for a year as a small clump of leaves, grow tall and flower the next year then die. Be sure to let the flowers fade and go to seed each year if you want to have this plant in your garden each year. This native bellflower may grow as tall as 5 feet before opening its light blue flowers in July. It is particularly attractive to bumblebees.
