The general name 'Zamia variegata' pertains to the cycad Zamia Picta Variegata. Not the plant that is the ZZ plant (Zamia zamifolia). I was wondering which you are actually growing? I think perhaps the Plant Database needs to separate these 2 and make entries for Zamia picta variegate and Zamia zamifolia varigata as these 2 appear to be those 2 plants, different plants.
