Rudbeckia maxima

Giant Coneflower
Rudbeckia maxima
Rudbeckia maxima

This large variety produces semi-double yellow daisies with tall dark brown center cones in summer, high over cabbage-like, blue-green foliage; an outstanding cut flower; drought tolerant once established; wonderful along borders or in containers

Ornamental Features

Giant Coneflower has masses of beautiful yellow daisy flowers with dark brown eyes at the ends of the stems from early to mid summer, which are most effective when planted in groupings. The flowers are excellent for cutting. Its attractive large oval leaves remain bluish-green in color throughout the season.

Planting & Growing

Giant Coneflower will grow to be about 4 feet tall at maturity extending to 7 feet tall with the flowers, with a spread of 3 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 24 inches apart. It has a low canopy with a typical clearance of 1 foot from the ground. Although it's not a true annual, this fast-growing plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.
