Rudbeckia maxima, is commonly known as large coneflower and is native to the central and southern US. It earns the common name by growing up to seven feet tall and producing numerous golden ray-shaped flowers with dark central cones, about three inches across. Another common name is cabbage leaf coneflower in reference to the plants large, powder-blue, basal foliage which can grow two to three feet tall.
It’s well behaved as a garden specimen as the rhizomatous roots are slow to move around and can tolerate a wide variety of conditions.
Deadheading flowers will encourage more blooms but be sure to leave some seed to ripen for visiting goldfinches and other birds.
These coneflowers attract both bees and butterflies and is a great way to add dramatic height to any garden design.
