Sorghum bicolor

Sorghum is a secondary noxious weed in Iowa because it can cause problems in corn and soybean fields, but it is also planted as a crop for syrup and grain. Horticultural selections have been made for color and height. Ornamental sorghum is an easily grown annual. The attractive seed heads can be used for fresh or dried arrangements. Many of the available selections are very tall and are a dramatic backdrop for other plants.
