Yes, it seems years improve the color.
Ok, your opinion ( Guru and you ) are more than enough to be sure is a Leeanum. I’m in dude because this was a gift from a woman in Portugal, she had a lot of pots, but they were insignes!! Later talking to her about it she plucked from one pot a division. Is true that she gives me from one plant that had not in bloom. I have a picture of the insignes. Thats what I thought it would be a insigne and not a Leeanum, but when it was bloom the first time I realiced something was wrong, and became to think in could be a Leeanum
