A: It takes an entire season for the grasses to reach their full height. It is a common misconception that one will see an entire prairie of 6 feet tall grasses blowing in the wind at any time of the year. It takes nature an entire season to grow the prairie grasses. Think of "tall in the fall". The tallest grasses grow in the bottomland areas which has more water available. The grasses on the prairie uplands will only grow to heights of 3 feet.
