I tried a Zamia here but it only made it through one year (only went down to 14F) and took all the way until the end of July to come back.

Another poster here has Cycas panzihuaensis growing in Zone 7.

Thanks. That looks like a very good website. I still might try the Prince sago, but I am also thinking about Cycas panzihuaensis and maybe considering a King sago if I give it lots of protection.

Cycas Tiatungensis is offered mail order from Yucca Do Nursery. Lots of cold hardy palms, too. Great website. Check it out.

Yucca Do looks good too. Lots of cold tolerant exotics there.

Still looking at the pros and cons of each cycad.

Cycas tiatungensis is a fast growing cycad, but will need protection when temperatures go below 20. Cycas panzihuaensis is suppost to be leaf hardy to 15 so that would need protection below about 17 or 18, but since its a really slow grower I am not sure how long it would take before it looks good after every winter. Both of these cycads are expensive so thats why I might consider a sago palm, becuase they are cold tolerant as well, but also cheap and common even at local nursuries. A sago palm will probably need protection below 20.

Thanks for your answers, and all suggestions are welcome.

I think you're on the right track re: sago palms. they are cheap, cheap, cheap,(especially from the big box stores, and I personally haven't found any better cold tolerance with C. taitungensis or panzihuaensis. Good luck.

Thanks. I am starting to lean more toward the sago palm becacuse even when in a pot I have seen them suffer no leaf damage when temperatures were in the low 20s. Also they are the cheapest and most convinent. On cold or wet days (in the winter) I will probably put a garbage can over it. Maybe if one night gets really cold (below 15) then I will put a heating bag in the garbage bin. I will look for some local sago palms as soon as I can because temperatures are now in the 40s and 50s during the night and average day temps are in the 60s.
