Hi BorS, nice to see you on the Lily forum! They look like some kind of Orienpets to me. Hard to say which one. Reminds me 'Conca d'Or', but it usually has wider petals. It is too tall to be 'Tarragona' or 'Yelloween'.
If it is Orienpet, it will multiply nicely for you. Orienpets are my favorite Lily division: very strong growers.

Hi Alina
I was thinking that they were Orienpets. They are more rubust than any of my Orientals. I looked up 'Yelloween' and the descripton at The Lily Garden said they face straight up. These definitely do not face up. Looks like both 'Conca d'Or' and 'Tarragona' though. I found one called 'Mistress' too that looks very similar. I'll probably never know but it is an outstanding lily.

Hi, It does look very much like Conca D'Or but any photo I have seen it has very brown anthers on the stamens. I have purchased one for this year so I will find out myself. The lily in your photo doesn't look like it has anthers or else they are very green - did you cut them off? The rest looks very close.

I pulled them off. I was a florist for over twenty years and always removed pollen from lilies so customer's table cloths/clothes didn't get stained.

Those are gorgeous. I'm envious.
