Kentiopsis oliviformis doesn't seem to care if it is Winter.

[Mangosteen]

The Kentiopsis oliviformis in my front yard here in south Orange County (CA) has decided to open its spear despite the fact that we entered the Winter season a couple of weeks ago. Night time lows have been in the low to mid 40's on average, days in the low 60's, but maybe its all the rain that  has fallen lately.

 

Any one else have Winter spears opening?

My Kentiopsis Oliviformis is continuing to grow right thru winter here in Huntington Beach as well. The sharpee mark on the emerging stem was put there two weeks ago. Although I have noticed they take awhile to open when you think it’s imminent.  
 

This guy was planted out June of 2021 as a 5G. This past humid summer, it exploded in size.  Seems super happy.

These are great palms for much of Southern California. When I lived in Fallbrook I had several in my garden there that never seemed bothered by cold or dry heat.

The two palms that I've noticed significant spear growth on regardless of this winter's cool temps and lack of daylight hours are my Chambeyronia hookeri and Burretiokentia koghiensis. The hookeri spear has grown a few inches over the past couple months where the koghi spear actually opened up and is now a new frond. 

Side note...your palm looks great Dale. Solid spear and pretty massive for a recently planted 5g!

KO also appears to be a good choice, with some provided shade,for the Arizona desert garden. I'm impressed with it's growth so far,in the location it's planted.

I put these in as KO 7g about 14 months ago.   They aren’t speed demons, but each leaf the opens is much bigger then the last, and since they are held pretty upright, they’ve gotten a lot taller.   They do slow down in winter here.

My real “winter” speed demons are Leptocheilos/Teddy’s.   They continue to double spike and pop all winter.  (Though winter is a relative term).  Maybe even picking up speed…

K. oliviformis (now Chambeyronia oliviformis) grow year round in my SF Bay Area garden. They slow a bit of course in winter but continue growing. A great palm for this area as they grow at similar speed to Archontophoenix cunninghamiana and are prettier in my opinion. They love lots of water!
