Texas FFA Nursery Landscape Practice Exam

Which of the following grasses has the longest winter dormancy period?

1. Bluegrass

2. Aphids

3. Scale

4. Zoysia

The correct answer is: Zoysia

The grass that exhibits the longest winter dormancy period is Zoysia. This species is known for its ability to enter dormancy during the colder months, typically from late fall through winter until temperatures warm up in early spring. Zoysia thrives in warmer climates, which causes it to rest and become less active during the cold season, leading to a vibrant growth period in the warmer months. In contrast, Bluegrass, while also experiencing dormancy, often shows signs of life sooner as temperatures rise compared to Zoysia. The other choices, Aphids and Scale, refer to pests and not types of grass, making them irrelevant to the question about grass dormancy. Therefore, understanding the growth habits and dormancy characteristics of Zoysia helps clarify why it stands out for having the longest winter dormancy period among grass species.
