Maximilian Sunflower

This tall perennial sunflower puts on a spectacular show in August and September with masses of large yellow-gold flowers. Native of the Great Plains, and now naturalized throughout much of North America, it was used by the Sioux and the Lacota for food. The tubers can be eaten like Jerusalem artichoke but are smaller, and the seeds can be eaten as a snack or sprinkled on salads. It is currently under investigation as a possible perennial oilseed crop. Because it develops dense clusters of roots, it is excellent for erosion control on slopes. It is a magnet for birds, wildlife and beneficial insects. Named after the German explorer Prince Maximilian who discovered the plant on an expedition to the Great Plains in 1832-34. Ht. 1-2m/3-6ft.
