There must be many types of Agave lophantha? Hetty's above plant doesn't look like any of the photos in the database.
Hetty do you know which one it is?
I do see where they can be hardy into zone 8.
Yes, but they have about the same hardiness. I grow A. lophantha 'Splendid' here in zone 6b/7a but I'm a bit of a zone pusher with that. However, my small one is doing just fine with a slight bit of winter protection to be on the safe side..
Lynn, I stick it under the carport or under the deck in a location where it still gets afternoon sun. Yes, our winters can be snowy and spring can be very wet. So far, so good.
That means I might have a chance at keeping one alive outdoors year round. Thanks for the information Tee. : )
I can put it on my covered porch for winter. It will get 1/2 day of sun.
One more question. Do you water it in the winter?
