What Is a Hardy Plant?

Hardiness of plants describes their ability to survive adverse growing conditions. It is usually limited to discussions of climatic adversity. Thus a plant's ability to tolerate cold, heat, drought, flooding, or wind are typically considered measurements of hardiness.

Do hardy plants come back every year?

If the plant is described as 'Hardy Perennial' it should stand up to average low winter temperatures and come up each year for several years. A 'Hardy Biennial' will build up a strong root and leaf system in its first year, survive the average winter and go on to flower, set seed and die off in its second year.

What is a full hardy plant?

Hardy plants can resist adverse growing conditions, such as frost, cold winds or drought, meaning they should survive (depending on the plant) year after year.
