Which of the following is a perennial?

• A. Goldenrod.
• B. Chicory.
• C. Queen Anne's Lace.
• D. Sunflower.

Answer: (A)

Perennial plants live for more than two years and come back year after year from the same root system. Goldenrod does exactly this: it has a persistent root network that survives winter and sends up new shoots each growing season, blooming reliably year after year. That continuing, multi-year habit is what makes it a perennial. In contrast, sunflowers complete their life cycle in a single growing season and die after producing seeds, so they are annuals. Queen Anne’s Lace is usually a biennial, meaning it grows foliage in the first year and flowers in the second, then often doesn’t persist as a long-lived plant. Chicory is commonly treated as a long-lived herb in many contexts, but in this list it’s not the standout perennial in the same way Goldenrod is, so Goldenrod best fits the idea of a plant that reliably returns each year.
