I got this plant when it was relatively small from Cistus Nursery. I think I have had it for about 10 years, although I could be off by a year or two. I have potted it up to larger pots several times in its life, and I think it will probably require a larger pot in a year or two. As I have mentioned before, I now pot all my wicked plants in clay pots that I can break with a hammer when I repot. Otherwise, they are too difficult to remove from the pot. Nice fancy pots are all well and good until it comes time to repot the plants that are in them, particularly when those plants are agaves or puyas!
I used to have a huge collection of 'Pets' that I kept in pots, but with our move and the general decluttering of the house and garden that goes along with putting a house on the market, I have gotten rid of most of them. This agave, however, has made the cut and will be coming to our new house. I should mention that there is really no place to store non-hardy plants over the winter at the new place, but I will think of some way to protect this agave! Some other plants that have made the cut are my Cussonia and Boophanes.
