What's the native? This plain red one?
"The genus is native to tropical and subtropical regions of the New World, from the southern United States (southern South Carolina west to southern Texas) and south to northern Argentina."
"Without exception, all Canna species that have been introduced into Europe can be traced back to the Americas, and it can be asserted with confidence that Canna is solely an American genus."
USDA plants database has 10 entries for Canna, 9 of which are species indicated as introduced.
Is this plain-leaved red-flowered one a particular species or a hybrid? Native to where?
