ID - is this a type of cane begonia? (pic)
These were grown this spring from seeds sort of resembling pinto beans that a neighbor passed along. They are about 4 ft. tall. The closest I can find on the "A to Z of Flowers" web site is some type of cane begonia. I'm completely begonia-ignorant, so forgive me if I am way off base. Thanks to anyone who can help me ID this plant!
