Are palm trees ferns or trees?

I am pretty sure they are trees....

SECOND ANSWER: There seems to be some disagreement whether palm trees should be called trees at all (having no branches but only trunks, leaf stems and leaves) although they often do reach enormous heights as far as plants go. Nevertheless they surely are not ferns (which reproduce via spores) but flowering plants.

Palms are neither a softwood (Gymnosperm) nor a hardwood (AngiOSperm).

Palms are members of the Arcaceae family of flowering plants. They have been termed "the princes of the vegetable kingdom."

Of course, due to their enormous size, palms are commonly referred to as 'trees.' If one falls on your car, you're not going to tell the insurance agent that the damage was caused by a flowering plant.

So, while you and I might call them trees, Palms are not scientifically classified as such
