Caryota gigas/obtusa

Considering this palm in 9b Northern California. From what I've read, it may be doable. Does anyone have any experience with these palms?

@Chavy87 I have tried here a couple of times in 9B / bordeline 9A Floriduh, and failed all of the times.  However, an important bit is they took heavy frost damage and just never grew back.  I would guess (without direct knowledge) that they'd do a lot better without frost, or with jusf a couple degrees warmer than my place.  Jusf a few miles Southeast of me, Leu Gardens has grown several to fruiting 40+ foot monsters.  But they are inside the "urban heat island," which definitely helps.

You could check @kinzyjr's spreadsheet of cold damage.  There should be some CA reports that should help!

Based off the data, cold wouldn't be too much of a concern. We may have a 2 or 3 days under 30 last winter.

Just be aware that these palms are monocarpic and will die a couple years after flowering.  According to Palmpedia they can reach 60' in height (big boy palm) in about 25 years.  Not really suitable for a small yard and a huge expensive removal project down the road.  But it's a beautiful palm.  Maybe it's doable in NorCal but is it worth it?

I am aware. It is unfortunate that they are monocarpic. As far as, is it worth it? Yes and no but I stopped keeping track of the money wasted on palms and tropical plants, along time ago.

Obtusa grows in Fresno, and urens will bloom and seed in Fresno. I dont know of an obtusa old enough to bloom in this area, but I know of at least 3 big juveniles, and one trunking palm in the Fresno area (Old Fig Garden, Sunnyside, Del Rey, Tower District). It's only a matter of time before one of them does bloom - likely the one in Del Ray which is the oldest and biggest. This is a picture of mine from a year ago. It's put on some size since then.

Here's one you can see on street view. I drive past this property almost daily - and it appears this one may be close to trunking as well.
