About this cultivar:

Rudbeckia maxima is an overlooked impact plant. This unique giant black-eyed Susan has a deciduous basal rosette of waxy blue foliage resembling a collard. In late spring through early summer, the flower stalks of Rudbeckia maxima can rise to over 7 feet tall. At the top of each stalk are large, wide, brown-green centered, yellow daisies. After flowering birds love to eat the seeds. See what I mean!?!? We should see it more often!

Specific epithet, maxima, means largest in reference to the large size of this Rudbeckia.

    About this genus:

    Rudbeckia (rood-bek-e-a) is a plant genus in the sunflower family (Asteraceae). The species are commonly called coneflowers and black-eyed-susans; all are native to North America and many species are cultivated in gardens for their showy daisy-like yellow or gold flower heads, some are even red or brown.

    The name was given by Carolus Linnaeus in honor of his teacher at Uppsala University, Professor Olof Rudbeck the Younger (1660-1740), and his father Professor Olof Rudbeck the Elder (1630-1702), both of whom were botanists. Rudbeckia is one of at least four genera within the flowering plant family Asteraceae whose members are commonly known as coneflowers; the others are Echinacea, Dracopis and Ratibida.

    Rudbeckia is a tough summer-flowering perennial grows almost anywhere that isn't full shade or a pond. It is a tough, low maintenance plant which makes it perfect for wet gardens. Where happy, Rudbeckia spreads into a slowly widening clump that gets more floriferous each year. Rudbeckia flowers attract butterflies and the seed heads are a favorite of goldfinches; and they look great in the autumn when the petals fall off. 

    As for partners, obvious ideas are grasses and other plants int he sunflower family (Asters, sunflowers etc). Try against dark backgrounds. Anyway, I think these look great anywhere.
