This Crème Brûlée isn’t so tasty
While we had above-average rain in early and mid-December, there has been very little precipitation since then. In addition, the coldest temperature we’ve had this winter was 28°F on January 2 and 3, and that only lasted for a couple of hours each time.
With this in mind, it’s even more baffling why my Agave guiengola ‘Crème Brûlée’ ended up like this:
Yes, this is a fairly frost-sensitive species (San Marcos Growers rates it hardy to 25°F), but I just don’t see how this could be frost damage.
I’ve never twirled an agave leaf before!
In addition, it’s not the pattern you’d see if the plant were rotting from excess moisture. That kind of damage typically starts in the crown and spreads outward.
Here, the rot starts toward the middle of the leaves and spreads from there.
The pups are affected as well.
I dug up the mother plant and the roots look fine.
I popped off the babies but after removing the rotting leaves, I was left with only one viable pup (on the right).
I have no idea what’s going on here. All I know is that I waited too long to intervene. If I had dug up the plant and removed the rotting leaves weeks ago, I might have been able to save the mother and more of the pups.
This isn’t the first Agave guiengola ‘Crème Brûlée’ I’ve lost. A much smaller plant succumbed to frost damage four years ago. (I can’t remember the damage pattern but it may have been the same or similar.) I suspect this species is not as hardy as reported, or else there’s a curse on it that only affects me.
I’m officially giving up on Agave guiengola, especially since its leaves sustain blemishes so easily. Even at its best, my plant was never as attractive as what you see here. There are plenty of other agaves that would be more rewarding to grow; I’ll let you know what I will plant instead.

After the snow here, I swore I'd never have another A. attenuata... and now I have three little guiengolas, oy. On the other hand, there are so many great-looking agaves :~) I'll be interested to see what you plant in the guiengola's place.
Have you tried laying down a thick layer of porous rock mulch? I only ask because the species grows on rock outcrops and the soil splatter could be depositing organic matter on leaves that normally receive none thus inclining them to rot. The variegate would likely be less hardy than the species, but blocking the leaves from soil splatter might improve the outcome for you.
Just a thought.

I know what you mean about A. attenuata. I've said the same thing so many times! My A. attenuata 'Ray of Light' made it through the winter with no damage, as did my much larger 'Boutin Blue'. But long term, A. attenuata is not a good fit for our climate--too hot in the summer, just a bit too cold in the winter.
I've had the same negative experience with Agave mitis [aka celsii] 'Multicolor'. I've killed two, and yet my regular A. mitis and my A. mitis 'Nova' are thriving. Go figure!
The sad thing is that I have plenty of rock mulch left over and could easily have protected this plant.
It was in the backyard, by the way, and while it wasn't covered with leaves, there were some bay leaves trapped underneath it.
Considering how good the roots look, I would think with such protection the plant would do well for you. Keep in mind, however, that these don't stay small and can get gigantic. See photos I took at RSN with Kent Houser of Mysterious Gardens for scale:

Of course, Kelly says that that is only occurring because of the RSN steroids they fertilize with, but still . . .
