Bismarckia opening a new leaf


Mauna Kea Cloudforest

Recommended Posts

I didn't expect this, with lows averaging near 42F and the latest week of freeze dropping temps down to 26F down there during the night and 59F during the day, the last thing I was expecting is a leaf to open. But indeed, it's opening. Lows near 50F and highs in the 75F range today. BTW, 26F didn't touch my bismarckia. Talk about acclimatization, bismarckia seem to have some pretty good genetics. Winter is just starting, so let's hope they continue to thrive.

We are in a drought, this probably really helps.

No, just the angel opens the wings to rise in to (palm)heaven! Just kidding though, mine does the same thing right this moment, but I am not sure whether this will finally be for good...

Is yours not doing well? I have six in the ground, and all are thriving, although the one that seemed to discolor easily is now deep purple, and it's not even in the cold part of the garden.

No it is well, but newest expanding leaf is still to tender to withstand imminent winter, so an unnecessary future loss! But I can not stop this bizzie rom growing further.

I had a leaf open up on the biggest one just before the freeze, it was still greenish. Nothing happened during the freeze, There is now a just a tiny hint of red/purple hue to it but it's barely noticable.

I do have one bismarckia that just discolors like crazy with temps below 45F. It's insane, it literally turns red-purple. Ironically, it's in the most cold protected part of the garden where it only saw two Mornings at -0.5C for 3-4 hours. So no freeze damage, but the discoloration is so intense that this palm just looks red. See photo below:

This I agree with, I have had this happen in AZ. A new emergent leaf has to become strong and that doesn't happen fast in winter. Axel, I have seem bizzies that try to hold on to the closed spear for a long while and then they just cant any more. Your weather cycling (warm/cold/warm) may have initiated the opening. I had one open in winter too, it took a long time to colorize, it was yellow for 5-6 weeks. At this phase I think it may be tender as Konstantinos says. If you get another cold snap before it colorizes, I think it would be good to cover that leaf.

Formerly in Gilbert AZ, zone 9a/9b. Now in Palmetto, Florida Zone 9b/10a??

You have to wait until substantial rise of temps in the following growing period. Such a late leaf may look healthy all the winter long and during spring and then one day in late spring to early summer you may realize that silver color of this particular leaf has changed to papery white!

I don't think you understand: it's been like that for quite a long time. This is the color when I bought it. This bismarckia stands out from all the other ones: it's just constantly reddish as a result of any temps below 45F. It has not been exposed to more than -0.5C this year for maybe 4 hours length, barely cold enough to lightly burn a nearby banana. When I bought it, it had already seen -2.5C in San Diego County.

I may end up with a permanently red bismarckia. I bought it for that reason because I was curious.

Yes, a new leaf was a little yellow-green when it opened about 2-3 weeks before the freeze. But this bismarckia is rock solid and the leaf is perfect, no frost damage. This one won't be opening a new leaf until next Spring. I have another bismarckia that is now opening a new leaf, we're supposed to hit the 80's today and night time temps are Summer-like, so the bismarckia will continue to grow in this weather.
