Cold Hardiness Zone Map - Palm Trees In Your State - What Growing Zone Are You

Updated: Sep 26, 2023

The USDA Hardiness Zone Map is a guide with regions characterized by a 10-degree Fahrenheit distinction based on yearly minimum temperature. This guide partitions North America into 11 separate zones. The higher the zone number, the hotter the region.

Data from the zone map encourages plant enthusiasts to look at their area's temperatures and climate information and figure out what plants will develop in their general vicinity. Remember, this guide just shows normal yearly low temperatures and doesn't think about imperative elements like soil types, precipitation, daytime temperatures, day length, wind, mugginess, and warmth.

Those components are imperative and assume a key job in sound palm development and advancement. A genuine model would be Portland, OR, and Austin, TX. Despite the fact that they are both situated in Zone 8, their atmospheres are drastically extraordinary.

Applying zone references

In the chart above, everything is broken down into zones. In the event that a palm is strong in zone 7, that implies it can withstand the most reduced temperatures of that zone. In the event that there is a scope of zones like 7-10, that implies it can thrive just in those zones and won't endure colder or hotter temperatures.


If you live in a microclimate, which is an area within your zone that may be warmer than your actual zone, you might be able to grow other types of plants and palm trees. This can occur from being near the water, blocked from wind, or other unique factors like conventional heating and cooling.

USDA Zones

Here is a list of zones with avg. annual low temperatures:

Zone 1: below -50 F (below -46 C)

Zone 2: -50 to -40 F (-46 to -40 C)

Zone 3: -40 to -30 F (-40 to -34 C)

Zone 4: -30 to -20 F (-34 to -29 C)

Zone 5: -20 to -10 F (-29 to -23 C)

Zone 6: -10 to 0 F (-23 to -18 C)

Zone 7: 0 to 10 F (-18 to -12 C)

Zone 8: 10 to 20 F (-12 to -7 C)

Zone 9: 20 to 30 F (-7 to -1 C)

Zone 10: 30 to 40 F (-1 to 4 C)

Zone 11: above 40 F (above 4 C)

Are The Growing Zones Changing Due To Global Warming?

With the changing climate, gardeners are keen to understand the USDA hardiness zones and how they are changing over time. This system helps gardeners and farmers to understand which plants grow best in specific regions of the country based on average winter temperatures. Global warming has caused the zones to gradually shift northward, resulting in some areas experiencing milder winters while others are experiencing harsher ones.

The USDA recently updated its hardiness zone map, which is now widely used by gardeners to determine which plants are likely to survive in their area. Whether you are a seasoned gardener or a beginner, understanding the updated hardiness zones is crucial in planning for a successful and fruitful harvest. So next time you ask yourself, "What garden zone am I?" make sure to check the latest USDA update to ensure you are planting the right seeds for your region.
