Gardeners' Notes:

I have kept "Uncle It" for at least five years in a 6" pot...then last year sat that pot on top of a 10"'s rooted through now I suppose.
I have seen photos of them growing in the UCLA botanical garden and really a lush looking haystack looking plant.
From what I can tell it takes much water to very little.The more,the better "It" looks.So to speak. Full sun. They could be better for rock gardens over being stand alone plants.
I think, they are not quite as potent as the desert Ephedra's I read from some source,someplace....
