I took this photo last month. Just haven't had enough time during the last few days to take some pictures. This is Agave lophantha 'Quadricolor', one of my favorite variegated Agaves. It's not hardy enough to take our winters, but I don't know what it is...we just can't resist a nice Agave. And, luckily, many of them will stay quite small for quite a long time when grown as a pot specimen.
