Which plant is biannual?

Which plant is biannual?

• A. Goldenrod
• B. Chicory
• C. Queen Ann's Lace
• D. Dandelion

Answer: (C)

Biennial plants complete their life cycle in two years. In the first year they focus on vegetative growth, often forming a rosette, and in the second year they flower, set seed, and then typically die. Queen Anne's Lace is a classic example: it grows low and leafy in year one, then in year two sends up a tall flowering stalk with its characteristic lacy white blooms and seeds. The other plants listed are perennials, meaning they survive and regrow for many seasons from roots or crowns, rather than dying after a second year. Dandelion, chicory, and goldenrod all persist year after year, so they don’t fit the biennial pattern.
