Curiosities: What are those tall, corn-like plants at Library Mall and in front of Bascom Hall?

A: They are broomcorn, a plant still used to make straw brooms, says Mohammad Fayyaz, head of the botany garden at UW-Madison. The plant was reportedly imported to the American colonies by Benjamin Franklin after 1700. Scientifically known as Sorghum vulgaris var technicum, broomcorn is closely related to sorghum, a grain crop grown in drier parts of the Midwest. Sorghum and corn are closely related.
