A Collection of Planting Zone Maps, Hardiness Zone Maps and Climatology Data for Gardening and Horticulture
總之﹐你可以種比自己區更耐寒的植物﹐不可以種數字更高的植物。 經常當你購買植物時﹐除了植物名稱﹑需陽光否的簡單說明外﹐還會有Zone X 的字樣﹐說的就是這植物可以種植的地區。 比如說﹐萱草Day Lily 通常是屬於第二區Zone 2 ﹐表示可以在Edmonton(亞伯達省艾蒙頓)﹑Regina(沙省雷振拿),以南的地方種植。

Despite the low plant biomass of arid regions, litter represents an important microhabitat for myxomycetes. For example, in the steppe zone of Eurasia, the intrazonal arboreal communities of the steppe and desert zones provide all of themicrohabitatsfor myxomycetes typically found intemperate forests(...
The most widely used system of plant hardiness zones was first developed by theU.S. Department of Agriculture(USDA) in the 1960s. The USDA’s Plant Hardiness Zone Map divides theUnited Statesinto 13 zones. Each zone represents a range of 10 °F (5.6 °C) for the average annual extreme...
individual plant species cannot be used in referring to all of the existing maps. In most cases they can be related only to the map used in assigning them. The two most widely used in this country are the Arnold Arboretum hardiness map and the "Plant Hardiness Zone Map" prepared by the ...
The new updated 2012 USDA Plant Hardiness Zone Map will help you determine which plants are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones. Now the map is an interactive GIS-based map, for broadband ...
aThe USDA plant hardiness map divides North America into 11 hardiness zones. Zone 1 is the coldest; zone 11 is the warmest, a tropical area found only in Hawaii, coastal Southern California and southernmost Florida. In between, the zones follow a fairly predictable pattern across the continent,...
