With a remarkable spotted pattern, signal orange anthers and edges frillier than kale, the blooms of the Starfish Iris bear a remarkable resemblance to the sea star that shares its name. It's not actually an iris either, though this Southern African beauty also goes by the name spider iris. Surrounding itself in a delightful vanilla fragrance, this drought-tolerant perennial is an exciting addition to a border or rock garden. Or let it take center stage as a potted plant.
