Trying to guesstimate the age of a new Coccothrinax Crinita

[Jayme J]

Picked up this C. Crinita yesterday and got it in the ground in my garden.  Trying to guessimate its age so I can plan around its estimated height for other plants around it.  Yes, I know they grow slowly, I just want to know around how old it is so I can estimate how tall it'll be over the years. I don't want to plant anything that will block his light. He's about 12 inches (30 cm) from crown to spike tip. Google's AI assistant says 3-4 years, but I don't necessarily trust that since it often gives really conflicting information.

From my experience with cocothrinax they are slow that one would be at least 15 years old if grown in my climate.

Knowing its age isn't going to help you much.  Growth rate is different in ground than it is in a pot.  Some palms grow much faster once they're planted but some (as this one probably is) will not grow noticeably faster.  As Richard said, more likely 15 years old from seed.

I’ve been seeing a few of these pop up at regular local nurseries here for reasonable prices lately.   

These two were for sale up the road and must have sold, as they are gone now….

They are slow growing, but grow fastest in South Florida conditions.
