Incredible growth for a 40 cm palm planted 4 years ago or normal?

[Palmfarmer]

My neighboor has two somewhat big palms in his backyard.  i asked him how old they where and the size when he bought them and he said 4 years and around 40 cm tall. i was stunned here is the pictures, is this normal? He never fertilized them or anything.  By the way could anyone try and identify the palms. I know it is a phoenix Canariensis but is it very pure? it looks that way to me. Also the washingtonia i suspect is a fillibusta, correct?

Washingtonias are weeds here in Socal. Birds drop seeds in my yard and if I don’t pull up the seedlings right away they are 12 feet tall before I can blink

yes they sure do but that fast is normal? and look at the Canary Island one. is this growth speed normal or are these genetic freaks?

Every climate is different. Palms will always grow much faster in their native habit. The 2 types of Washintonias that grow here in California grow extremely fast at least in my area. Unfortunately I am not a fan of them otherwise I’d have in my yard.
