Cycas glauca

Cycas glauca is a blue-grey cycad endemic to Timor and Sumba in the Lesser Sunda Islands, growing in seasonally dry lowland woodland. It wants full sun, warmth all year and a very free-draining soil, with generous water in the summer wet season and a much drier spell from May to October.
