Don't they just put a new year on top of last year's chart?

Welcome aboard, NYCpalmManiac.

Let's see the palms you're a maniac about...

You can zoom into each state and get a closer view!

darn! still a zone 6b. I was hoping I could grow palms outside with no protection.:lol:

Tulsa was moved from zone 6b to 7a, and my parent's Oregon beach home was moved zone 8b to 9a. Hooray! 😆
Also, Oklahoma's native palms in McCurtain county are now in zone 8a.

Too bad to those of us who is hoping thrive it as a Zone 7b palm 😛

wait... Erick , how did your zone go UP, concidering how cold your winter was? Did you not go -30? Doesnt the record low define the hardiness zone?

Not sure, but I think they used average winter lows from 1996 - 2005. Does anyone know?

Correction:
"Zones in this edition of the USDA Plant Hardiness Zone Map (PHZM) are based on 1976–2005 weather data."

More detail:
"The zones in this edition were calculated based on 1976-2005 temperature data. Each zone represents the average annual extreme minimum temperature for an area, reflecting the temperatures recorded for each of the years 1976-2005. This does not represent the coldest it has ever been or ever will be in an area, but it reflects the average lowest winter temperature for a given geographic area for this time period. "

I think this link has the new Canadian map:

Thanks Erik

Damn, only a pixel away from heaven...

Edit: my link only went to the main page (sorry) instead of my location.

Thanks to all for the detailed maps. I had no idea my 7a was so close to being a 7B (Harford County Md. just off the Chesapeake Bay).
On another note, still have yet to completely cover my newly planted (August 2011) Trachy's. They've been protected fairly decently with bubble wrap around a cage and christmas lights but no protection on top. The top of the fronds are open to the elements with no damage (at least not from the temps). And from the latest forecast (at least for the next week or so) the temps won't really be getting below freezing. Don't get me wrong though, as soon as I hear something nasty is coming my way i'll do what I need to do so they don't take a hit.

still have yet to completely cover

Maybe you won't have to this winter 😀

That certainly is my hope especially since the average temp has now started to increase again. Albeit very slowly. I Can't let myself forget we still have another full month of real winter ahead.

Bah! I am still 7A. No upgrade to 7B o 8A for me.
