What Do Hardiness Zones Mean?

Department of Agriculture. It divides North America into eleven zones by minimum average annual temperatures. The lower the number is , the lower the temperatures in that zone.

What is hardiness in plants?

Hardiness refers to how well a plant will survive cold temperatures. Where the USDA zones fall short, however, is that they don’t account for other factors. These include freeze dates, freeze-thaw cycles, the effects of snow cover, precipitation, and elevation.

What are the limitations of the USDA Zones?

If you live in this area, you may want to use the Sunset climate zones. This system uses more than just the minimum temperatures to determine which plants grow best where. They also use the length of the growing season, summer temperatures, wind, humidity, and rainfall.

What is a USDA zone?

If you are new to gardening, you may be confused by some of the terminology associated with plants. For instance, a USDA zone explanation may be necessary. This is a useful system for determining what plants will survive and grow in certain areas of North America.

How many degrees of temperature difference are there in each zone?

The lower the number is, the lower the temperatures in that zone. Each zone represents ten degrees of temperature difference. Each zone is also divided into “a” and “b” segments. These represent five degrees of temperature difference.

Do annuals need zones?

The zones are not important for annuals since these are plants you would only expect to survive the summer months, or one season. For perennials, trees, and shrubs though, be sure to check the USDA zones before you put them in your garden.

What is hardiness zone?

A hardiness zone is a geographic area defined to encompass a certain range of climatic conditions relevant to plant growth and survival. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by annual extreme minimum temperature.

What is the temperature scale used to define USDA hardiness zones?

Temperature scale used to define USDA hardiness zones. These are annual extreme minima (an area is assigned to a zone by taking the lowest temperature recorded there in a given year). As shown, the USDA uses a GIS dataset averaged over 1976 to 2005 for its United States maps.

What zone is Puerto Rico in?

In 2012 the USDA updated their plant hardiness map based on 1976–2005 weather data, using a longer period of data to smooth out year-to-year weather fluctuations. Two new zones (12 and 13) were added to better define and improve information sharing on tropical and semitropical plants, they also appear on the maps of Hawaii and Puerto Rico. There is a very small spot east of San Juan, Puerto Rico that includes the airport in coastal Carolina, where the mean minimum is 67 degrees F (19 C), which is classified as hardiness Zone 13b, the highest category, with temperatures rarely below 65 °F (18 °C). The map has a higher resolution than previous ones, and is able to show local variations due to things such as elevation or large bodies of water. Many zone boundaries were changed as a result of the more recent data, as well as new mapping methods and additional information gathered. Many areas were a half zone warmer than the previous 1990 map. The 2012 map was created digitally for the internet, and includes a ZIP Code zone finder and an interactive map.

What is the minimum temperature a plant can withstand?

For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C).

When did Arbor Day update hardiness zones?

In 2006, the Arbor Day Foundation released an update of U.S. hardiness zones, using mostly the same data as the AHS. It revised hardiness zones, reflecting generally warmer recent temperatures in many parts of the country, and appeared similar to the AHS 2003 draft.

Where are the warmer zones?

In the United States, most of the warmer zones (zones 9, 10, and 11) are located in the deep southern half of the country and on the southern coastal margins. Higher zones can be found in Hawaii (up to 12) and Puerto Rico (up to 13). The southern middle portion of the mainland and central coastal areas are in the middle zones (zones 8, 7, and 6). The far northern portion on the central interior of the mainland have some of the coldest zones (zones 5, 4, and small area of zone 3) and often have much less consistent range of temperatures in winter due to being more continental, and thus the zone map has its limitations in these areas. Lower zones can be found in Alaska (down to 1). The low latitude and often stable weather in Florida, the Gulf Coast, and southern Arizona and California, are responsible for the rarity of episodes of severe cold relative to normal in those areas. The warmest zone in the 48 contiguous states is the Florida Keys (11b) and the coldest is in north-central Minnesota (3a). Puerto Rico has the warmest hardiness zone in the United States at 13a. Conversely, Fort Yukon, Alaska has the coldest hardiness zone for any city in the United States at 1a.

Overview

European hardiness zones

The table below provides USDA hardiness zone data for selected European cities:
Owing to the moderating effect of the North Atlantic Current on the Irish and British temperate maritime climate, Britain, and Ireland even more so, have milder winters than their northerly position would otherwise afford. This means that t…

United States hardiness zones (USDA scale)

The USDA system was originally developed to aid gardeners and landscapers in the United States.
State-by-state maps, along with an electronic system that allows finding the zone for a particular zip code, can be found at the USDA Agricultural Research Service (USDA-ARS) website.

Australian hardiness zones

The USDA hardiness zones are not used in Australia. The Australian National Botanic Gardens have devised another system more in keeping with Australian conditions. The zones are defined by steps of 5 degrees Celsius, from −15–−10 °C for zone 1 to 15–20 °C for zone 7. They are numerically about 6 lower than the USDA system. For example, Australian zone 3 is roughly equivalent to USDA zone 9. The higher Australian zone numbers had no US equivalents prior to t…

Canadian hardiness zones

Climate variables that reflect the capacity and detriments to plant growth are used to develop an index that is mapped to Canada's Plant Hardiness Zones. This index comes from a formula originally developed by Ouellet and Sherk in the mid-1960s.
The formula used is: Y = -67.62 + 1.734X1 + 0.1868X2 + 69.77X3 + 1.256X4+ 0.006119X5 + 22.37X6 - 0.01832X7

The Azores range from 9a to 11b and Madeira ranges from 9b to 12a, 9a and 9b found inland on the highest altitudes such as the Mount Pico in the Azores or Pico Ruivo in Madeira. The Spanish Canary Islands hardiness zones range from 8a to 12b dependi…

South Africa

South Africa has five horticultural or climatic zones. The zones are defined by minimum temperature.

Effects of climate change

The USDA map published in 2012 shows that most of the US has become a half zone (5 °F (2.8 °C)) hotter in winter compared to the 1990 release. Research in 2016 suggests that USDA plant hardiness zones will shift even further northward under climate change.
