Giant coneflower (Rudbeckia maxima) is a tall perennial.

It has clumps of sea-green foliage. The lower leaves are 8 to 12 inches long and 5 to 7 inches wide; the upper leaves, 2 to 6 inches long and wide. The flowers sit horizontally on tall stalks rising from the center of the plant. The petals bright yellow and slightly droopy surround a brown and green cone.

The plant attracts butterflies and bees, is deer- and rabbit-resistant and can be seen in the Pollinators Garden at the Franklin Park Conservatory and Botanical Gardens.
