Which plant is considered an annual in central Illinois?

1. Daisy

2. Marigold

3. Maple

4. Oak

The correct answer is: Marigold

Marigold is considered an annual in central Illinois because it completes its life cycle within one growing season. This means that marigold plants germinate from seeds, grow, flower, and produce seeds all in the span of a few months. They thrive in the warm growing conditions of summer and typically die off with the first frost in the fall. In contrast, daisies can be perennial, meaning they can live for more than two years, returning seasonally. Maple and oak trees are both classified as perennial species—specifically, deciduous trees that can live for many decades. Their life cycles involve years of growth and maturity before they start to reproduce, which sets them apart from annual plants like marigolds that follow a much shorter life cycle. Thus, marigold is the only option listed that fits the definition of an annual in central Illinois.
