Our single Sago has been in the ground for many years, in a pot for many years prior and gave us the surprise of a cone this year (this is a male plant). I was hoping to find a nearby Sago with flowers (the female plant), but the nearest Sago is putting out pups and not blooms.
I will be on the look out for a bona fide female Sago for the garden. The Sago is a very old plant. I liken it to the Gars in the Sound waters which may be a stretch, the gars are prehistoric.
