Large Sabal ID

[Chester B]

This palm is located at a nursery outside of Salem, Oregon.  This is considered 8B and gets more cold in winter than what we would see in the Portland metro area.  The palm was imported at a larger size and I have been told it is a Sabal Palmetto.  The thing is this palm is absolutely massive compared to the palmettos I am used to seeing in Florida.  Is this more robust due to our cooler temps?  In the winter of 2016 this palm was subjected to temps in the teens (no idea how low though) and spent 2 or 3 days below freezing.  After enduring this it defoliated, but I was told came back with avengeance that summer and looked better than it did the year before.  I wish I could get a person in for scale but I can tell you that you can easily walk under the fronds.  Trunk is super thick.  It's been a warm summer here so I hope to go back in fall to see if some seed actually develops.  You can see my hands can reach around the petioles.

Big palmetto?  Other??  I'd love to hear your thoughts.

could be sabal palmetto, the leaf stems(petioles) are relatively thin, most of the big sabals have thick ones.  An Oregon grown palmetto will likely look different than a florida grown one.  Florida palmettos grown in deep shade can be pretty wide it the crown, 15' wide is not uncommon.

You know I was thinking the same thing.  I watched some videos of Causiarum and such, and the petioles you could not get your hands around where I could on this one.  I have seen some monsterously wide palmettos in the shade, but I don't think they had a trunk this thick.
