Senecio "mandraliscae" or serpens??

I bought this plant in a garden centre, without a name, just for aesthetic reasons.
I can't give it a name for sure... although I think mandraliscae is the right one.... considering that mandraliscae is a taxon of mysterious origin..... :-)

Re: not Castellanosia caineana!

Hi Juster.
No, living in southern Sardegna island (Italy).
Yes, the plant is a beautiful one.... but I am not so happy to have grown it for years, just hoping it would "turn" in what it should be....

not Castellanosia caineana!

Hi. I have grown this cereoid from Rowland's seeds in 2002; I bought them as Castellanosia (now Browningia) caineana... but it obviously is not that plant... even if on the web you can find pictures of very similar small plants named that way... so, may be the same error was done more than one time....

Re: Identity crisis

...nowdays we have planty of A. cultivar/hybrids.. and they give a lot of self sowing seedling (that, of course, are all mixed hybrids) in any collection...: so, I would not put a name to a plant witout it as there is a high probability to give it a wrong one....

Sedum mocinianum or piaxtlaense

I bought, as many of us, this plant as S. hintonii: a species that seems not to be in cultivation, at the moment... So, it can be mocinianum or piaxtlaense... The shape of the Leaves seems to fit piaxtlaense but I think it to be mocinianum as the flowering stem is a bit less than 4cm (it is said to ...

Re: Sedum mocinianum / piaxtlaense

This is Sedum paixtlaense, its flowers and flower stems are noticeably different from Sedum mocinianum. A very nice plant, too. .. but I am doubtful about it being S. piaxtalaense as the original description says: <<rosette: lax>>; on the other hand, it says <<rosette: dense>> about S. mocinianum.....

Sedum mocinianum / piaxtlaense

I recently bought this plant in a garden center; it was labelled Echeveia globulosa: obviosly an error. Now, the plants is the one generally sold as Sedum hintonii, but certanly it is NOT that species. It could be S. mocinianum or S. piaxtlaense.... : the stem and leaves resemble those of S. mocinia...

Re: GYPSUM

You can get Gypsum alright, but you may have to buy a 25kg bag! I have used it for over 20 years and Cacti thrive on it if you use it wisely. I guess it helps to unlock some of the base key elerments and nutrients for the plants to absorb. Use it sparingly, I use a table spoon full to a bucket of p...

Re: GYPSUM

Thanks to all contrubutors, but I think many of you misundestood the question: gypsum is a calcium sulphate and not a calcium carbonate, like limestome for example. That is a BIG difference, being gypsum valuable in providing calcium to the soil lowering (and not raising) the soil pH, being acidic.....
