Agave? ID

[Chester B]

Was gifted this plant today. The owner doesn’t know anything other than it’s an agave that came from Texas. Winter hardy here in Portland zone 8b/9a. And can tolerate our wet winters. I think it’s an agave, very fleshy with chainsaw like teeth.

Thats a form of Agave funkiana .
 

There are a few forms of lopantha that are narrow and long leafed and overlap closely as well . Some consider funkiana to be a form of lopantha.

Here are some gallery links. The pictures seem to skew towards matching your agave to a narrow form of lopantha, but I’ve seen that generally identified as funkiana.

Agave xylonacantha is another that looks similar in pictures but different in person. It’s a slightly larger plant

@Meangreen94z many thanks!  At first I didn’t see the N in funkiana!

Time to read up on the new acquisition.

Yeah, initially I thought Xylonacantha, but the center stripe says Funkiana.  They are all closely related, I think...  If I recall correctly they are dry area agaves, but Lophantha and Xylonacantha do fine here in FL with our swampy weather and torrential rain.  Lophantha grows like a weed here.  Here is a good hardiness thread on agaves:

Yeah all three do well in wet climates. xylonacantha isn’t as hardy as the others. Lopantha and funkiana burned but came back from single digits in extended wet icy conditions(2/21). Xylonacantha will burn and come back from high teens in wet icy conditions, based on my experience last winter(2/22). Lopantha and funkiana took no damage. 
 

Some stubby forms of lopantha look only vaguely similar to the long narrow leaf forms of lopantha, and funkiana. If you put those two next to xylonacantha in person the differences are obvious. Xylonacantha is distinct. I own all three.
