And is the same plant.

Very good-looking plants. I think it is a Sedum but I'm not sure which. Hopefully someone else will comment

If it helps, this is the same plant with flower. The plant blooms in January. Unfortunately, to this day I have not been able to identify it and I do not know if anyone will succeed.

Hmm, that looks like an Echeveria flowers.

LOL, before you posted the flowers, I thought it might be a Graptopetalum.

That last one looks like completely different plant - leaves seem to be short and wider. In first 2 photos, they are much longer and narrower. I am not considering color of the leaves (which is also very different) since that varies a lot according to light plant receives.

Rina, after you pointed that out, I've a look at the last photo again, to me it seems like someone cut off a flower stalk and stuck it into a pot to propagate, because those leaves look like the leaflets on a flower stalk, LOL, no rosette at the base?

I think the 1st & 2nd pix are 2 different plants. The leaf shape in the 2nd pic center plant is different than in the first, more tapered, not a difference from lighting.

I too was thinking Graptopetalum for the 1st pic. Agree that the last pix is a blooming Ech of some kind.

Wow Frank, you are good, this is it. I don't think I could have done without your help. Thank you very much all. I'm verry happy.

All 4 pictures represent the same plant but under different conditions. The particularity of this plant is that the leaf cells are seen with the naked eye. These cells form a very fine pattern on the leaf.

And indeed the flowers appeared, atypically for an Echeveria, on the main stem as you say. That's how the plant blooming, I dont cut off a flower stalk and stuck it into soil.

I found on the web this picture of Echeveria Carnicolor. Flowers are also on the main stem.

Andrei,

Haha, believe it or not, I have done it, re. cutting a flower stalk off and stuck it into mix to propagate! Of course at the time not realizing it was a flower stalk, just thinking it was a looooong side shoot... It went on to flower, then continue growing after flowering, amazing and it was an Echeveria pulvinata! Succulents are tough plants, LOL.

I have never seen E. carnicolor in real life, only from photos online... So it looks like it behaves the same way as E. nodulosa, which also flowered from the tip...
