Queen palms : how often do they have green trunks ?

[Nakheel1412]

Hi,

About 16-17 years ago, my mother bought 3 S. romanzoffianas ;
They basically didn't grow over the years (because of a severe manganese deficiency?), therefore I decided to transplant 2 and get rid of the 3rd ;

The thing is, one of them seems to have some green trunk
There's supposed to have grey trunks, don't they? I've searched the web but couldn't find any picture of a specimen with a green trunk ;

On top of that, even though this one spent 15+ years in a full-sun spot, the trunk didn't fully turn grey, rather some parts are green or dark brown/black, how is that ?

It probably is a regular romanzoffiana, yet I don't understand why the trunk is partially green...

Any idea on what's going on?

Thanks in advance !
(PS : I would have given it some manganese, but couldn't find it on the market here)
EDIT : The white spots are remnants of mealybug infestation ;

Queen trunks are quite variable. This one in my front yard is striped but most are solid gray at this point. The one pictured is 20 years old.

Very wide nodes! Is this an indication of bigger leaf bases?

Just very vigorous growth. Most nodes are more than 12" apart on my queens. They're fed and watered heavily and aren't subjected to freezing temperatures most winters.

Hi @Jim in Los Altos !
Actually there's some green on your palm too !

Thanks a lot for the info, at least if this one dies on me I won't feel like I've lost a gem !
