Rudbeckia maxima
Giant Coneflower
Giant coneflower (Rudbeckia maxima) raises yellow flowers with tall brown cones above a low mass of broad blue-green leaves. The contrast between bold foliage and slender flower stems makes it a useful large-scale perennial accent.
Its structure combines clumping growth and upright growth. Growth is moderate. Leaf retention varies with winter conditions.
Choose a site in full sun or partial shade. Provide humus-rich, well-drained soil.
