Biennial Flowers
Biennial flowers are plants that take two years to complete their life cycle. During the first year, they typically grow roots, stems, and leaves, and then they enter a dormant phase during the winter. In the second year, they resume growth, produce flowers, set seed, and then die. Here are some well-known examples of biennial flowers:
- Foxglove (Digitalis purpurea)
