Bellflower

Campanula is one of several genera in the family Campanulaceae with the common name bellflower. It takes its name from their bell-shaped flowers—campanula is Latin for "little bell".
The genus includes over 500 species and several subspecies, distributed across the temperate regions of the Northern Hemisphere, with the highest diversity in the Mediterranean region east to the Caucasus.
The species include annual, biennial and perennial plants, and vary in habit from dwarf arctic and alpine species under 5 cm high, to large temperate grassland and woodland species growing to 2 metres (6 ft 7 in) tall.
