CANNA
Commonly known as Canna lily, Indian shot plant
All flower JUL-AUG
Genus of about 50 species of perennials from forest margins and moist open areas in forests in Asia and tropical North and South America.
If protected from frost they are easily grown to flowering requiring an average 6-8 hours sunlight over summer.
The rhizomes are rich sources of starch and have been used as foodstuff historically and was once a staple food crop in Peru and Ecuador.
Hundreds of hybrids exist from complex crosses and distinction between them has become blurred.
