Bring the native beauty of the prairie to your garden beds with the dramatic Giant Black Eyed Susan. Low, gray-green foliage clusters send up tall stalks 4-6 feet tall topped with yellow coneflowers in early summer. Blooms are loved by finches and butterflies. A low-maintenance plant that excels in average and poor soils. Deer resistant. (Rudbeckia maxima)
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
4-6’ tall x 18-36" wide. This isn’t your typical black-eyed Susan! Rudbeckia maxima is extremely tall and adds drama to sunny wild or meadow plantings as well as enlivening traditional cottage or formal gardens. A beloved native of the midwest, the blue-green paddle-shaped foliage lends terrific textural contrast to gardens filled with green, and is also called 'cabbage leaf coneflower' for this reason. Yellow coneflowers with large black seedheads emerge on tall stems in mid-summer and create an airy, wild effect. A low maintenance perennial, Rudbeckia maxima will do well in average soils with average moisture, but thrives in a consistently moist environment. It can be grown in part-shade, but bloom will be lessened. Leave the flower stalks to dry in place and you’ll attract a host of finches in the early autumn, as well as encourage reseeding next spring.
