Most sources list this agave as hardy only in zones 9-10; Plant Delights Nursery extends it to Z7-10; and there are reports of hardiness in zone 6 (see links below). While in Pennsylvania, I picked up a tiny 2nd-year plant at the HPS/MAG plant sale, and set it in our rock garden to see if it would survive – but it didn't. Many years later, now in Texas, I bought another specimen, this time of the 'Quadricolor' variety, at the sale area at Peckerwood Garden. This time, it shouldn't expire from cold, although excess moisture is still a concern. But planted in well-drained soil in our rock garden, it's been doing great for several years now. The fourth color, pink, supposedly develops when the plant receives plenty of direct sun. I've noticed a hint of that, but for the most part it sticks to a striking contrast of cream, dark green, and light green.

I'm afraid our experiment was unsuccessful: the plant was lifeless the next spring
