E,horridus makes miracle comeback!
This plant I bought in 2007,was planted out and..never grew a new frond. I think it was simply too much shade,although C&S and even a Sago palm in that same light thrive. Yet,it was a lack of all day sunlight I now know that caused it to sit until I couldnt take it any longer and dug it up with it's last two leaves in early summer this year. Those two slowly withered..and its seemed a sure gonner. Still,I put the now potted horridus into hot full sun area-the best I have..and just today I saw the new growth.
I read long ago-never give up on Cycads-no matter how dead they look. And it is so true.
