It almost looks as though Picasso himself spattered red paint on to the rich yellow blooms of the Picasso canna. In any case, the vivid color combination is certainly an attention-getter, even though this canna is considered a dwarf. Like all cannas, once it starts blooming, it doesn’t stop until frost if you keep deadheading. Then, if you want to save the plants for next year, you can simply dig them up and store them in a damp medium like peat some place where it’s cool (but not freezing cold).
