Castor Bean Plants (Ricinus communis) re-seed themselves at my front door Canna border. Before a killing frost, they reach up to thirteen feet. This photo is taken from my front door porch, looking down through a vine wreath. I love the red colors of the 'Carmencita' variety. Each year, they come back 'true.' I usually cut the berries off through the summer but when the plants get tall enough for a ladder, I leave them alone so that they will make beans that will sprout the next season.
