Sometimes called Elephant Ears, this is a bold specimen perennial that needs a moist location. Plants form a clump of large, jagged-edged green leaves. Purplish black stems rise above in summer, bearing long spikes of bright-yellow daisy flowers. Superb for the back of the border, or at the waterside. An unusual centerpiece for a tub or large container. Both the flowers and leaves are great for cutting. Slugs can be troublesome. Clumps may be divided in the spring, every 3 to 4 years.
