What are these cacti called?

[sandywong929]

Hi everyone,

I hope this is the right session to put my post, as I can't find a Succulent & Cactus session.

I have bought a few beautiful cacti for my tabletop garden, yet, I don't know their names. Could someone please tell me what are they called? Thanks a lot!

The plant on the far right in the photo is a Sedum, possibly S. rubrotinctum. One common name for it is "Jelly Bean Plant."

The cactus in the center might be a member of Echinocactus ... or not. It could just as easily be a member of Astrophytum. It's hard to be certain.

The one on the left, well, I have no idea.

Why not ask the people who sold them to you?

Sandy,

The one on the far right looks like a species of Crassula, of which there are many. I used to have a link to a retailer that had numerous pictures but the link is dead now. Perhaps a Google search will lead you to an identification.

The middle one appears to be a form of bishops cap...

The one on the left is throwing me, but I think it might be a cristated form of another cactus. This is a mutation of the meristem (growing tip) and the fact that it is also varigated (another mutation) makes me think that is the case...

Didn't see any that were eureka moments..., heres [url=https://www.cactus-art.biz/gallery/Photo_gallery_variegated/Photo_gallery_variegated_&_albinos.htm]variegated mutations[/url]...



Maybe Cereus forma cristata variegata? I.d.ing a mutant won't be easy...

Thanks everyone for your kindly help. Thru some reference books and other gardeners' help, I think I have more or less figured these out.

the left one - Cereus sp. forma mostruosa cristata variegata
the middle one - Gymnocalycium mihanovichii
the right one - Sedum Rubrotinctum (or Sedum Pachyphyllum, not very sure)

Kisal, I wish the people who sold me the cacti know the name of the plants. I bought it in a local market in Hong Kong. At most, the people in the market may know the common name of the plants, and it's in Chinese too.

Thanks for sharing what you learned! It adds a little bit of information for all of us.

Plant sellers who don't know the names of the plants they're selling is a common situation everywhere. It can make it difficult for those who need the information in order to provide proper long-term care for the plants. I'm glad you were able to find out what cacti you have!
