This perennial sunflower is named for Prince Maximilian of Wied-Neuwied, (near Koblenz) a noted German naturalist, who encountered it on his travels in North America.
It grows widely in the prairie states and is a towering plant suited to large gardens or the back of a border.
The taller it becomes the more of its chocolate scented flowers develop until it becomes a dominant feature of any garden.
Depending upon your attitude it's either a majestic, stately plant that should command a prominent position to be admired by all or a useful giant that can hide the garden shed.
It loves hot, dryish soils and is very attractive to bees, butterflies and small birds.
