I would suggest giving your plant more light - it looks OK, but slightly pale in color and leaves/rosettes are opening up - that is usually sign of plant wanting more light. It is not too bad, but could be better :) It looks like there is not enough 'soil' in the pot - parts of plant look quite low/deep inside.

Best mix is fast draining. I do not know what you use for mix (it would also help to know where you are...general location and/or growing zone should be posted next to your name). Mix that is grainy and mostly inorganic works very well for succulents. Plant would be fed by fertilizer if needed (I actually hardly ever fertilize succulents, and they are in a mix of grit, sifted perlite and turface only). But for winter, it may be best to reduce temps, watering and fertilizing - that also depends on where on this earth you are...

It's nice but I don't think that's pulidonis. It lacks it's robustness and the extremely distinctive center rosette. Agreed though that it needs more light.

Agree with Rina that it's better to plant too high than too low.

As Dave said, it doesn't look much like pulidonis - but plants grown in insufficient light are often hard to ID...they loose proper color and the form. Did it ever bloomed? Flowers should help to ID. Regardless what plant it is, it needs more light.

Dave's photos show how good plants could look when all bunched up - rather than dividing. But it is personal thing, and they could be grown singularly or with few/more offsets left together.

Here is what my pulidonis looked like in May not long after I got it. It still has a little bit more of a tight rosette than OP's. If it's not a pulidonis, it certainly looks to be a relative. But again, could just be do to lighting. I have some sedeveria Letizia that no longer looks anything like when I first got it because I have struggled with it so much.

My plant(s) turned out being E. agavoides and not E. pulidonis, but have gone through the same light issue. Ignore the flowers as they are not true examples but damaged or aborted blooms. You can see when I purchased the plant and after a summer in the sun. I thought the difference was incredible!

I keep them in a large bowl now. There is no farina on these plants.

Katherine, your plant is a beauty! Good job!

Crenda this is agavoides grown here in Nv. Burns in our intense sun so just grown in bright light. Do we in fact have the same plant? This is why I'm a mess at plant id.

I am in total agreement with you on the difficulty in identifying these plants! I think there are different E. agavoides just like there are many Echeveria. I have seen lipstick and ebony advertised. Mine are NOIDs, and I'm ok with that.

This is another agavoides that I have. Looks completely different and more like yours. It tends to burn in the sun, too. Again, NOID.
