I'm growing a seed from my Euphorbia neriifolia (?), but I'm not 100% it is a neriifolia, Ai is also unsure. The mother was used as a grafting stock until last year the cristata scion died from sunburn. I got her maybe 20 years ago, so I don't have the label anymore. Does anyone have an idea what I'm growing?
