New USDA plant hardiness map released

I guess we need to wait for EU translation. Not that it would make that much of a difference

I went from slightly over the border of zone 10 to in the middle of zone 10, so now there’s no doubt

It could make it harder to keep some species that need colder winters.
Scotts pine, mugo pine and Japanese white pine are ones that need a cold winter
Winters here have been getting warmer which has raised my concern about being able to keep these species here in the future

I’m not really concerned about that. Our winters are still plenty cold and long. Maybe that will be a problem in another 30 years, but not yet!

I am on Long Island. The last few winters have been very late and very mild here.

I think we got a total of 6 - 8 inches of snow max from 2 storms for the whole winter where I am. Other than 6 or 7 days, it didn't get very cold.

Upstate and west of NY had a very different winter.

Adair is a pine man...and he's in a warmer climate. Yes?

See...I must be in a thick of a microclimate. As clearly I've seen colder winters. I went from being able to have a Ryusen in my landscape for years. To if I did it now. I might as set fire to my money.

Adair is in NE Georgia which is 7b, 8a pr 8b according to the map. He keeps JWP and JBP. He doesn't keep scots or mugo pines.

The reason JWP may fare better is if they are grafted onto JBP or another species that prefer/tolerate warmer climates

Right...but Scots are very common in the UK and their winters are milder than we see as well.

Don't get me wrong. I can understand your concern. But I see these on benches warmer climates than you. So...I think yours end of the day. Will be fine.

*I spend most days with ones across the pond. Truly... love the character found in their trees. We have a similar seasons. They just are milder..

Ohhh let me show you a juicy number...hold on.

Adair tried to talk me into a Scots pine. I thought he had one. I ended up going neagari JBP for the roots of course. But I thought he had one.

P. sylvestris has the widest natural range of any pine on the planet and can be found from the Mediterranean region all the way to the arctic circle, iirc. Provenance is important, but they tend to be very adaptable, and folks definitely grow them down south. I also have several older, ungrafted JWP that grew wonderfully in zone 8a N GA and haven't skipped a beat here in 6a MI.
