This lovely flowering plant is not Echeveria setosa but a close relative, perhaps a hybrid with pulvinata. The main way I can tell is the leafy parts of the flower are pressed up against it, not pointing out away from it. That is a pulvinata trait (also found in some other Echeverias) and not characteristic of setosa. Is is possible the plant is 'Doris Taylor'?
Thank you very much for share your thoughts. Personally i have no idea...I bought this plant as setosa..but I agree with you..sometimes nurseries sell plants no true to name..Also another point is the color of the flower..which is no red as setosa..
