It's a tall tropical looking flower that I've seen planted in the center of dome-shaped flower beds in city parkettes (Toronto). The flowers are delicate looking red-orange, on a long stalk, (like calla-lily) with long, deep-green leaves that "go up" (ie they don't flop over). It's not a calla-lily because it doesn't have stamen showing.
They seem to be used by the city and also apartment buildings for height and colour in the center of the annual flower beds.
