Fascinating topic! There are so many other variables besides just the minimum temp when it comes to plant hardiness, especially palms. For example I (probably) lost a Trachycarpus this year, but because the freeze came very suddenly after temps up above 9-10C. (50F) I think it would have survived a similar freeze if we'd had normal (for us), colder winter weather leading up to it. It wasn't fully dormant. The overall climate of an area also makes a difference. Phoenix dactylifera are known with certainty to have survived -17C or even lower, during very infrequent freezes in the US Southwest. But that's a very dry desert climate, and temperatures just a couple days after the freezes were back above 12C during the day. With bright clear days being the norm in winter. They could never survive a temperature that low in more humid places like the UK, or even the southeastern US.
Here in the Willamette Valley Oregon, Trachycarpus fortunei seems to be slightly hardier than Cordyline australis. But Cordyline almost always re-sprouts from the base if killed to the ground. This might be of interest: In the USA, Cordyline australis is never sold or labeled as such. It is almost always labeled as "Dracaena Spikes", or sometimes "Dracaena indivisa Spikes". So weird. I've grown Trachycarpus wagnerianus (some say it's a form of fortunei) in several gardens because its much shorter petioles and smaller fronds are a lot easier to accommodate in small gardens. I think its a fabulous palm for small spaces.
Just found your video, hello from Tucson AZ!

And of course some would argue palms never go dormant...but they do slow their growth 😏
Hi! Friends.

Good to hear from you and it is always interesting to know how others are gardening. Regards Stephen
I Love this Episode ;), Can I grow Bismarckia Nobilis in Pot Permanently?
I think it would grow too big to be a particularly long term pot plant. Regards Stephen
@@thehorti-culturalists thanks very kindly Stephen.
Cheers. John
All my cordylines here in south london were trashed by the cold this past winter,i'm devastated
they usually reshoot. Regards Stephen
