Where in California does this palm look it's best?

And what challenges do you have in growing it.

Please share a photo of your California Triangle Palm.

To piggy-back...

Please also share how much sun yours gets.
(I've heard they like sun but am curious whether they can also do well in partial shade)

All pics are from LA and SD aside from the last one growing in the heart of San Francisco. I have seen healthy mature ones in Palm Springs, CA, as well! Very adaptable palms! 

These grow great here in SoCal as well as in the Bay Area. Here’s mine planted out from a 5G  2-1/2 yrs ago. This was about 3ft max, maybe less when planting. Super happy with the growth rate. The fence is 7ft tall so the Decaryi is easily 8ft+. @iDesign , this is Facing North so it’s completely protected from the South sun by the wall at its back.  Little protection from the West by a large Colocasia.

That's quite a healthy specimen you have there Billeb.

I've never seen one growing up here in Northern California, and I can't imagine they would look as nice as yours with our wetter winters.

What do you suppose is the cause of the brown leaf tips on some of these? Maybe they're not growing in the most optimal conditions?

Mine have died in cold or cool and wet conditions.  That is 50's/60's during the day and 30's a night.  I can grow Archontophoenix, and Howea without issue here.  Archontophoenix  and Howea can be damaged by cold but don't die.  I think that they would do best in the southern 1/3 of the state.  There are nice specimens here in Santa Barbara but only in select microclimates.

Where in California do you live?

Recently, there was a post on this palm growing somewhere in the east bay, I believe. I can't remember the details, but I haven't seen one before, so they are few and far between in the Bay Area. 

Toughest of all Chysalidocarpus in California. They grow moderately fast, can handle 120 degree temps, eat up all day sun and require only moderate amounts of water. 
 

Once they get a certain size they aren’t as elegant as some members of the genus but only Pembana grows much faster in Socal but they have much higher cultural requirements to look their best. 
 

By far the two best growers for me here in the heat and elevation.
