The most commonly used lawn grasses in the U.S. are divided into what types?

1. Perennials or annuals

2. Grasses or broadleaved

3. Warm season or cool season

4. Spring or summer

The correct answer is: Warm season or cool season

The correct classification of the most commonly used lawn grasses in the U.S. is based on their growth patterns and seasonal preferences, which are categorized into warm season and cool season grasses. This distinction is essential for understanding how different grasses thrive in varying climates and temperatures. Warm-season grasses, such as Bermuda and Zoysia, grow best during the warm months of the year, typically from late spring to early fall. They are well-suited for regions with long, hot summers. In contrast, cool-season grasses, like Kentucky bluegrass and fescue, flourish in the cooler temperatures of spring and fall, making them ideal for areas with milder summers and cold winters. Recognizing this classification helps gardeners and landscapers select the right type of grass for their specific regional climate and intended use, ensuring optimal growth and health of the lawn. The other options do not address the seasonal growth habits of grasses, making them less relevant in the context of lawn grass selection.
