Purple cornflowers are what type of plant?

• A. An annual
• B. A shrub
• C. A perennial plant
• D. A biennial

Answer: (C)

Understanding how long a plant lives helps you classify its life cycle. A perennial lives for more than two years and returns each growing season from the same root system or crown. Purple cornflowers have a robust root system that can survive winter in many climates, so new growth and flowering can come back in subsequent seasons. That ability to persist and reflower year after year is what makes them a perennial in gardening practice. In contrast, annuals complete their entire life cycle in one growing season and die, while biennials live for two years and typically flower in the second year. Keep in mind that climate can influence behavior—for example, in very cold climates cornflowers may behave more like annuals, but in milder gardens they often persist as perennials.
