What are the main differences between 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, 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.
