Biennial

A plant that completes its life cycle in two years. A plant will typically establish itself in the first year by producing leaves and stems; whilst in the second year it will flower, seed and then die. A biennial is also sometimes used to describe a short-lived perennial.

This life cycle is not the most common in plants, but examples include:
• Foxglove (Digitalis purpurea).
• Wallflower (Erysimum cheiri).
• Sweet William (Dianthus barbatus).
