Cactus Dahlia cultivar

Cactus Dahlia cultivar, with typical backward curling petals
The dahlia was declared the national flower of Mexico in 1963
 Many sources state that the name "Dahlia" was bestowed by the pioneering Swedish botanist and taxonomist Carl Linnaeus to honor his late student, Anders Dahl, author of Observationes Botanicae
 The tubers were grown as a food crop by the Aztecs, but this use largely died out after the Spanish Conquest
Attempts to introduce the tubers as a food crop in Europe were unsuccessful
