Close up of Canna flora in outdoor Jefferson Market Garden in New York City.
Canna (or canna lily, although not a true lily) is a genus of 10 species of flowering plants.
The flowers are composed of three sepals and three petals are small and hidden under extravagant stamens. What appear to be petals are the highly modified stamens or staminodes.
The flowers are typically red, orange, or yellow or any combination of those colours, and are aggregated in inflorescences that are spikes or panicles (thyrses).
