Hardiness zone 11: lowest average temperatures of 40°F to 50°F or 4.4°C to 10°C. About the USDA Hardiness Zones. This map shows higher zones than the accepted USDA map allows for—the USDA hardiness map simply assigns Zone 11 for anywhere with an average annual minimum temperature above 40 F. If they are following the zone system, then each zone is 10 F higher than the last one, making Zone 12 at 50 F and Zone 13 at 60 F. 10 of 11 across (12 cm), packed with star-shaped, pale yellow flowers adorned with a pale purple stripe down the center of each petal. This information is based on a USDA standard, called hardiness zones , which considers the environmental conditions that plants need to thrive in certain locations. Obtain Plant Hardiness Zone Information. 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). It has been adapted by and to other countries (such as Canada) in various forms. The hardiness zones are developed by the Department of Agriculture in the United States. 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. Mount Isa has three climatic stations with more than a ten-year record. Planting Zone 11 is found in Hawaii, the Florida Keys, Puerto Rico and a few small areas of the Continental United States. Blooming in late spring to early summer, the eye-catching flowers rise on long, slender stalks until the plant goes dormant in summer. This evergreen shrub produces pretty, bicolor flowers followed by edible fruit. The USDA system was originally developed to aid gardeners and landscapers in the United States. These examples prove that local topography can have a pronounced effect on temperature and thus on what is possible to grow in a specific region. Listed alphabetically by Scientific name first and common name second. The map is divided into thirteen distinct 10ºF zones, which are further divided into sub-zones of 5°F. In this method, common plants with known limits to their range are used. Zone 11. Based on the minimum ten-year average winter temperatures, plant hardiness zones maps have been progressively developed, first by the Department of Agriculture (USDA) for the United States and then more or less applied to the rest of the planet. [17][18][19], The formula used is: Y = -67.62 + 1.734X₁ + 0.1868X₂ + 69.77X₃ + 1.256X₄+ 0.006119X₅ + 22.37X₆ - 0.01832X₇, For practical purposes, Canada has adopted the American hardiness zone classification system. Higher zones can be found in Hawaii (up to 12) and Puerto Rico (up to 13). Unless specifically noted, all zones in this section are USDA zones. The Australian National Botanic Gardens have devised another system more in keeping with Australian conditions. Plant name: Filter. Zone 4 lies between the Arctic Circle and about 64–65°N, with cities such as Oulu and Jokkmokk, zone 5 (south to 61–62°N) contains cities such as Tampere, Umeå, and Östersund. Warm region gardeners are often frustrated by their inability to grow many types of plants that are not hardy in their zone. Kiruna is the major exception here, which being located on a hill above frost traps, is in zone 5. The 2003 map placed many areas approximately a half-zone higher (warmer) than the USDA's 1990 map. Keep in mind that local variations such as moisture, soil, winds, and other conditions might affect the viability of individual plants. 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. [8] The Canadian government publishes both Canadian and USDA-style zone maps. 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. If you are planning to buy a shrub, perennial or tree, you need to make sure that this new plant will tolerate year-round conditions in your area. This shows the importance of taking heat zones into account for better understanding of what may or may not grow. [21] The cooler UK summers must be considered. Find your garden’s hardiness zone by Zip Code.. Gardeners rely on USDA Hardiness Zone Maps to tell us which plants survive and thrive locally. Hardiness zones Hardiness Zone. [22] The RHS hardiness ratings are based on absolute minimum winter temperatures (in °C) rather than the long-term average annual extreme minimum temperatures that define USDA zones.[22]. It consists of three archipelagos, the Portuguese Azores and Madeira, belonging to zones 11a/11b and 11b/12a respectively and the Spanish Canary Islands, part of zones 12a/12b. One is in zone 4a, one in zone 4b, and the other is in zone 5a. [8] Research in 2016 suggests that USDA plant hardiness zones will shift even further northward under climate change. Carolina, Puerto Rico has the warmest hardiness zone in the United States at 13b. In Sweden and Finland generally, at sea level to 500 metres (1,600 ft), zone 3 is north of the Arctic Circle, including cities like Karesuando, Pajala, and Rovaniemi. Different locations in the same city are suitable for different plants. [citation needed]. The 1990 version of the USDA Plant Hardiness Zone Map included Canada and Mexico, but they were removed with the 2012 update to focus on the United States and Puerto Rico. [citation needed], Sunset publishes a series that breaks up climate zones more finely than the USDA zones, identifying 45 distinct zones in the US, incorporating ranges of temperatures in all seasons, precipitation, wind patterns, elevation, and length and structure of the growing season. The hardiness category is indicated for each individual plant species. [citation needed].

Another notable example is Waksmund, a small village in the Polish Carpathians, which regularly reaches −35 °C (−31 °F) during winter on calm nights when cold and heavy airmasses from the surrounding Gorce and Tatra Mountains descend down the slopes to this low-lying valley, creating extremes which can be up to 10 °C (18 °F) colder than nearby Nowy Targ or Białka Tatrzańska, which are both higher up in elevation. In 2003, the American Horticultural Society (AHS) produced a draft revised map, using temperature data collected from July 1986 to March 2002. All these coastal locations have one thing in common, though, which are cold, damp summers, with temperatures rarely exceeding 20 °C (68 °F), or 15 °C (59 °F) in Longyearbyen. The first attempts to create a geographical hardiness zone system were undertaken by two researchers at the Arnold Arboretum in Boston: the first was published in 1927 by Alfred Rehder,[1] and the second by Donald Wyman in 1938. Hailing from the temperate shores of the southeastern Mediterranean, these bright, peppery-scented bulb flowers are not winter hardy. Zone 11 (40 to 50): Beets, mangos, begonias, and chives are especially productive in this zone. The foliage of long, grasslike, basal bright green leaves emerges in late winter and dies back as the flowers appear.

The warmest zone in the 48 contiguous states is the Florida Keys (11b) and the coldest is in north-central Minnesota (3a). USDA zones 9 to 11 are areas with lowest temperatures at 25 to 40 degrees F. (-3-4 C.). Many plants may survive in a locality but will not flower if the day length is insufficient or if they require vernalization (a particular duration of low temperature). Plant Hardiness Zones. The USDA Plant Hardiness Zone Map is a valuable agricultural and horticultural reference. [2] The Arnold map was subsequently updated in 1951, 1967, and finally 1971, but eventually fell out of use completely.

Conversely, Fort Yukon, Alaska has the coldest hardiness zone for any city in the United States at 1a. Considered the standard measure of plant hardiness, the USDA Plant Hardiness Zone Map is based on average annual minimum winter temperatures. Reviewers noted the map zones appeared to be closer to the original USDA 1960 map in its overall zone delineations. Estonia is divided to warmer West and North coast (Tallinn 6a, Haapsalu 7b, Kärdla 7a, Kuressaare 7a, Paide 6a, Rakvere 6a, Narva 6a, Viljandi 6b) and colder inland (Tartu 5a, Valga 5a, Võru 5a). Sydney residents are split between zones 3a and 4b.

The USDA rejected the AHS 2003 draft map and created its own map in an interactive computer format, which the American Horticultural Society now uses. Snow acts as an insulator against extreme cold, protecting the root system of hibernating plants. 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. 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). As an example, Quebec City in Canada is located in zone 4, but can rely on a significant snow cover every year, making it possible to cultivate plants normally rated for zones 5 or 6.
