the biggest problems with collections like this ... is two fold ... first... the pot has no drainage ... so it wont make a mess at the funeral home ... this can lead to nightmare watering problems ... especially ... secondly.. if two of the plants have diverse watering needs ... e.g. many ferns do not like swampy soil ... but the others might ... once you get your IDs ... you should head to the houseplant forum ... and ask them how to break up this pot .... into 3 different pots ... and that way.. you will have 3 remembrance plants ... or all three into a bigger pot with good media.. and drainage ... theres a lot of plants in that rather small pot ... think of it this way ... this plant came from a florist ... it was made up.. for high impact and wow ... a nursery .. where they sell houseplants.. might have done it much differently .... AND THATS WHAT YOU HAVE TO FIGURE OUT.;. FOR LONG TERM SUCCESS ken

Gymnocalycium is the genus, but as far as species I don't know.

thank you so much it just grew and i left it , because it don't look like a weed

Thanks! Edit - Apparently this is the "Elegant Stinkhorn" with the... interesting common name of "faeces carota" lol. I wonder if that means what I think it means :D
