Canna (or Canna lily, although not a true lily) is a genus of approximately twenty species of flowering plants. The closest living relations to cannas are the other plant families of the order Zingiberales, that is the gingers, bananas, marantas, heliconias, strelitzias, etc.

Canna is the only genus in the family Cannaceae. Such a family has almost universally been recognized by taxonomists. The APG II system of 2003 (unchanged from the APG system, 1998) also recognizes the family, and assigns it to the order Zingiberales in the clade commelinids, in the monocots.

The species have large, attractive foliage and horticulturists have turned it into a large-flowered, brash, bright and sometimes gaudy, garden plant. In addition, it is one of the world's richest starch sources, and is an agricultural plant.

Although a plant of the tropics, most cultivars have been developed in temperate climates and are easy to grow in most countries of the world as long as they can enjoy about 6 hours average sunlight during the summer. See the Canna cultivar gallery for photographs of Canna cultivars.

The name Canna originates from the Celtic word for a cane or reed.

Campanula (pronounced /kæmˈpænjuːlə/ Cam-pá-nu-la) 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 about 300 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 m tall.
