None have anybody saying about in the garden. It does prick the thinker to read its distinct from Caribbean Roystonea's. Maybe the Royal palm that will grow all over warm California. Right next to your Beaucarnea.
I went to the Kew checklist in anticipation that I could then tell you it is not an accepted name for a Roystonea since I have never heard mention of it anywhere. But, to my surprise, it is an accepted name. But that is all it says, no info to offer other than "SE. Mexico to C. America"
As you know Dean,many Veracruz plants grow easily in California- Agave attenuata is another- whereas the Caribbean plants are hit and miss.
The fact it grows so close to Texas makes me wonder how many palm or just plain exotic plant collectors ignored them as being the common Roystonea's?
That quote "distinct from the Caribbean Roystonea's" (Wiki) is really tantalizing!
