Adonidia merrillii Help

[2hp]

I've had this Christmas palm (Adonidia merrillii) for about two months.

Can someone help me identify what's amiss here? Is this a disease or something else?

Where are you located?

This looks like sunburn to me.  I am guessing you are somewhere in the Southwest.

What cold temperatures is it seeing this time of year (assuming you're in the Northern Hemisphere, but perhaps not).

I'm in San Diego, CA.

Cold at night as low 40F last month

That's cold for Adonidia.  I would say Adonidia are "hypertropicals".  Maybe someone from your area will chime in to collaborate or disagree. Good luck!

Was it indoors before this? Almost looks like the sun is burning it a tad

Outdoors at nursery.

Adonidias do not survive well in CA. They require high daytime temps and warm nights, lots of sun and high humidity. They are also sensitive to cool/chilly temp as well as outright cold. In CA's Mediterranean climate esp on the coast, days are too cool and nights too chilly for an uber tropical palm like Adonidia. The CA climate is great for people but awful for tropical palms. If you want to grow tropicals, SFL (or HI) is the place to be (credit Beverly Hillbillies).

While they are rated to only 30F, I have seen some mature ones beachside in Ormond Beach, FL. 4 years old +, and appx 5 feet tall ,and some monster 15 footers right next to a house, about 1,000 feet from the Tomoka River, in Flagler Beach, FL thrive with no particular extra care.I covered up my newly planted (in August/2021) Adonidia, with a scrap piece of HVAC flexible duct, for our foray to 30F last week. The neighbor who only used a sheet on his has visible freeze damage on his leaves.
