Perennial Plants

How can I tell if a plant is an Annual or Perennial?

Annuals and Perennials vary depending on where you live. If you want a perennial, shrub, or tree to survive and grow year after year, the plant must tolerate year-round conditions in your area, such as the lowest and highest temperatures and the amount of rainfall. If you are Zone 5, any plant that is Zone 5, 4, 3, 2 and 1 would be a perennial in your area, and anything zone 6, 7, 8, 9 or 10 would be an annual.

Certain areas of your yard could be hot spots and might be able to tolerate one zone higher.

Note: If the map that displays your zone appears inaccurate, you may be in a microclimate.
