Cold Hardiness Zone Map - Palm Trees In Your State
Updated: Feb 23, 2019
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 areas 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 the 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 to zone 7, that implies it can withstand 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.
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)
