Forms a neat mound of spikey blue-gray leaves. Flowers occur only after decades of growth, so I'll forget about those. Should be just about hardy around here (Pennsylvania), as long as I can keep winter wet from killing it. I've tried growing hardy agaves before, but never got them through more than one season. In Pennsylvania I tried them in hypertufa troughs, which I could bring into the garage over winter – but I don't have a record of their survival. Now that I'm in Texas, where I've grown a good number of Agave species from seed, I'm trying again. The seedling in the picture at left (photo taken in August) lives next door to an even smaller saguaro cactus.

This plant used to grow in our garden, but it slipped away...
