Plant Hardiness Zone Map

Let’s start by giving a glance at the US Plant Hardiness Zone Map of the state.

Plant Hardiness Zone Map for Wyoming


Wyoming has a semi-arid, continental type of climate with warm and moderately wet summers and cold winters.

Wyoming summers tend to be warm, with the average high temperature ranging from 75-90°F in the peak of July in the plains, whereas the highlands above 2500 meters experience 70-75°F. 

Winters are cold and extreme in a few parts and the highlands.

Average low temperatures during January are in the cold 0-18°F range across different areas and elevations in the state.


Wyoming is a dry state with an average precipitation of 10 inches; lowlands receive sparse rainfall in the range of 8-10 inches, while the higher elevations average 15-20 inches.

Snowfall in the mountain ranges reaches up to 200 inches, while the plains also accumulate significant amounts during the winter.

Soil Type

The below map shows the ecoregions of the state.

Now, let us see the distribution of soil orders in these regions with the help of the table below:-

Soil Order Of Wyoming

Soil / Sub OrderLocationCharacteristics
Entisols/Orthents and FluventsIn the Wyoming basin and northwestern great plains1. Orthents are found on recent erosional surfaces.
2. Fluvents are the more or less freely drained Entisols that formed in recent water-deposited sediments.
Alfisols/CryalfsIn the Rocky mountains region.1. Cryalfs are the cold Alfisols that occur mostly at high elevations.
Aridisols/ArgidsIn the Wyoming basin and northwestern great plains.1. Argids have an argillic or natric horizon
Mollisols/Cryolls, Ustolls, and AquollsCryolls in the Wyoming Basin, Ustolls in the high plains, and Aquolls in the southern Rockies.1. Cryolls are the cool or cold, more or less freely drained Mollisols.
2. Udolls are the more or less freely drained Mollisols of humid climates.
3. Aquolls are the wet Mollisols.
Inceptisols/CryeptsIn the middle Rockies.1. Cryepts are the cold Inceptisols of high mountains or high latitudes.
