Every palm that is in the ground-z5 Iowa

What happens every fall....into winter,is you get this ratcheting downward of temps.

Here we usually get a strong serge of cold that pushes temps back below normal
and then the temps recover and stay above normal until the next adjustment downward...
but as we all know,sometimes it doesn't let us back up...anyway-

If we get a decent cold push in Sept/Oct and it follows significantly warm weather-
then having 5"+ rain and temps 75/85F apparently even a week of 28/32F(nights) is enough to
for those youngsters to jettison their leaders....

As I mentioned,it would be fun in a lab (greenhouse with a freezer 😀 )to gradually take
these cold hardy palms colder and colder letting them adjust each time....
Probably see palms that can take 0(F) over and over-they do loose their elasticity after a while though..

The scientist in you...

The best scenario would be lots of rain during summer, and none in Fall as temps cool.
Even better would be the "warming" promised-threatened for winter, not summer.

Just a Q...are takil, tesan, princeps ALL fortuneivariants?
i.e. just "mutations" of the same thing?

I've thought of doing that experiment with various Sabal minor ecotypes. One of these years.
Speaking of Sabal, the Lous look great there.

Glad to hear about the needle palms. Not news to anyone, but they really are very tough.

The Sabals have been a big surprise,they have had divided leaves
for a couple year but they are raising the up on taller petioles-very cool!

I have not posted for a bit and I see that your trachy's reaaly gave a push this year good job
