Conditions Comments: American century plant is large beautiful agave with sharp leaf tip spines. It is prominent in the landscape and best used in mass or as focal point. It also does well in pot (large) culture. It benefits from some extra moisture in very dry conditions, but is very tolerant of heat and xeric conditions. It can take light shade better than some other agaves. But should be protected from teen winter temperatures to avoid damage.
