Rudbeckia maxima (Coneflower)

Here's a bold and exciting native plant that's perfect at the edge of your pond or stream. It has huge powder blue leaves 2–3' tall from which flower spikes appear to 5–6' in June and July with large deep yellow coneflowers. Blooming into September, it prefers deep, moist soil, but will thrive in average garden conditions as long as it is kept moist. Maxima makes quite a statement.
