Agave id#2

[TexasColdHardyPalms]

These two plants were mixed in with havardiana and obviously arent havardiana. First and third pic is a shaded one, second and 4th are full sun. This agave is smooth on top and rough on the bottom of the leaf.

Size 11 shoe for scale. Also these slightly burn at 10f

It looks like a hybrid of Salmiana, possibly the "Green Goblet" type.  They tend to have the bluish bands and widely spaced marginal teeth, but most of them have rough tops and bottoms to the leaves.  Here's some variants that might help identify yours, if it is a Salmiana type:

It's also possible that it's a hybrid of Havardiana with one of the bigger green ones like Gentryi, Salmiana or Montana.  Or it could be a non-silver form, sorta like the ones shown at Kew:

Hmm. Interesting Merlyn...   It isn't a green havardiana, but I didn't even know that existed.

I bet the Agaveville forum people could tell you what it is in about 30 seconds...or less!
