This palm was grown from a seed found under a royal palm in Hawaii. We have grown them for over five years now. The problem is they don't look like a royal to me. They look more like a Washatonian. Could you please tell me if these are juvenile royals or another type all together.
I believe it is in the Washingtonia family. I can't say what specific tree, either a robusta or filiferia, but you won't be able to tell that until is starts trunking.
