Maximilian Sunflower, Max Sunflower, Helianthus dalyi
A bold statement in the landscape, Helianthus maximiliani (Maximilian Sunflower) is a tall perennial with rigid, hairy stems clad with long and narrow, coarse and hairy, grayish-green leaves, usually folded lengthwise, and a profusion of brilliant yellow flowers, 2-3 in. across (5-7 cm). Produced from late summer into fall over about a six-week period, each flower features up to 15-19 bright yellow rays surrounding a darker yellow central disk. They are borne on their own stalks and from the leaf axils. A valuable plant for wildlife (bees, birds and butterflies), this big and robust prairie perennial is a delight in large perennial gardens and wildflower meadows. It is not suited to the small perennial border as it needs room to spread.
