How long does a perennial weed live?

A perennial weed is defined by its ability to live for more than two years, which is why the correct answer is that it survives for more than two years. These weeds have a root system that allows them to regrow each growing season, often leading to their persistence in gardens and agricultural settings.

Typically, perennial weeds can survive through various environmental conditions, and their life span can extend to many years, sometimes even decades, depending on the species and conditions in which they are growing. This long life cycle makes them particularly challenging for land management and requires strategic methods for effective control.

Other choices suggest either a short life span or variability, but these do not accurately reflect the characteristics of perennial weeds. Instead, they are identifiable by their cyclical growth over multiple seasons, which is a defining trait of perennials.
