Question: 1 / 400

What type of weed germinates in the spring and develops a rosette?

Annual

Biennial

The correct answer is that a biennial weed germinates in the spring and develops a rosette. Biennial weeds have a two-year life cycle. During the first year, they typically germinate from seeds in the spring and then grow into a rosette of leaves. This rosette stage allows them to gather energy and nutrients from their environment while minimizing exposure to adverse conditions, such as heat or drought. In the second year, they bolt, flower, and produce seeds, completing their life cycle.

Annual weeds, on the other hand, complete their life cycle in one growing season, germinating, growing, flowering, and dying within that period. Perennial weeds live for multiple years and can reproduce by seeds as well as vegetatively. Winter annuals germinate in the late summer or fall and grow during the cooler months, but they do not typically form a rosette as part of their primary growth phase in the spring like biennials do.
