This species is way cold hardier than most sources claim.

In the UK they get killed at 18 F by winter moisture. When you keep them dry in winter they are able to take 5 F.

Planted in 2009 in sunny cactus garden. In August 2015 central bud stem and two bud stems from pups emerge. Central stem is over 13ft. by 9/23/15 and covered with buds beginning to open. Photo sent.

No watering except rain and marine layer fog on California central coast, diminished by drought and climate warming.

Easy to care for plant. Water well in spring/summer then let dry out, then water again. In fall/winter (in the Northeast) don't water but every two months approx & keep in a sunny window.

Once spring returns & frost has passed, put back outside...

Not a very interesting looking agave (to me)- tight rosettes of narrow, hairy, stiff dull-green leaves with sharp, scary-looking terminal spines. Looks sort of like a thick-leaved yucca or a messy Agave victoriea-reginae. Some obviously think it is beautiful, though, as it is often used as a container plant.
