They don’t freeze and “rise from the dead” in my experience. Once dead, they stay that way, unlike Jesus. They are a warm/moderate/hot climate plant. They can withstand moderate frost, but not completely freezing. There are many varieties but family and friends here who have attempted to grow them in areas where they get several weeks of sub-zero winters have lost them if they were exposed.

Google “yucca yellow leaves”. It looks like a lot of people have discussed this online in various fora. Here is one such discussion. Hope that helps!

@lilikoi Thanks. Already tried google though, and haven’t turned up with the answers I need, so I came here. :)

@DarkScribe Thanks for the thoughts. Yucca is actually very common here on Cape Cod, even though they are warm weather plants. The garden store who sold it to me told me to expect them to yellow out for the winter, and green up again in the spring. (They aren’t open for the season yet.) I cant imagine they’d all be dead when the neighbors’ are OK?
