Definition of Biennial Plant: Characteristics and Examples

📚 Quick Study Guide

🌱 Biennial plants complete their life cycle in two years. ☀️ Year 1: Focus on vegetative growth (roots, stems, leaves). 🍂 Year 1: Often form a rosette (low, circular arrangement of leaves). 🌼 Year 2: Flowering, seed production, and then death. 🥕 Examples include carrots, parsley, onions (some varieties), foxglove, and sweet William. 💧 Proper care in both years is crucial for successful flowering. 📅 Understanding their life cycle helps optimize planting and care schedules.
