I think the last one is Synadenium grantii var. rubrum

Agree with Carol; the last one was known for quite a long time as that, but all putative Synadenium are back to Euphorbia. Due to a long and tortured taxonomic snafu, this is currently being called Euphorbia bicompacta 'Rubra' - an ID I personally do not find acceptable or accurate.

Please be aware that this plant is dangerously toxic.

Your first plant is Portulacaria afra.

It is hard to pin down the second, but that may be a Crassula multicava or possibly another species.

I think you'll find that the accepted taxonomical name is Euphorbia bicompacta var. rubra. And it is not any more toxic than most other species of euphorbia....sap from any species can cause a reaction with those that are sensitive to it. Not everyone has the same degree of sensitivity but care should be taken when handling any euphorb.

As for care, as you most likely know, the first tenet of successful
container gardening, especially when dealing with succulents, is having
drainage holes at the bottom of the containers. Only exception is bog
and aquatic plants.

Sorry to disagree with GardenGal, but this plant has a well-documented record of poisonings and is especially dangerous. It often causes long-term eye damage.

I have abundant documentation to support this point.

She was not disagreeing, but saying there are many other Euphorbia that are equally dangerous. Those most popularly kept in the captivity of a pot would likely be the most notoriously culpable, merely from increased access.

Vic, to which Kalanchoe species are you comparing the thickness of your #2 plants' leaves?

It is good to know that Euphorbia's sap can cause serious irritation to mucous membranes (eyes, nose, mouth).

"the latex can produce extremely painful inflammation. Therefore, spurges should be handled with caution and kept away from children and
pets. Latex on skin should be washed off immediately and thoroughly.
Congealed latex is insoluble in water, but can be removed with an
emulsifier such as milk or soap. A physician should be consulted if
inflammation occurs, as severe eye damage including permanent blindness
may result from exposure to the sap", see https://en.wikipedia.org/wiki/Euphorbia#Irritants

Thank you iochrama for bringing this to our attention. Information (even if a little exaggerated, I think) is much better than serious complications.

As often as euphorbias are discussed here, on the Perennials forum or the Cacti and Succulents forum, anyone growing them should be well aware of their potential toxicity. Even the sap (latex) from your Christmas poinsettia can cause distress to those who are sensitive. But allergic sensitivity will vary widely from individual to individual. I have grown many different species of euphorbia over the years, both hardy forms as well as the more tropical succulent species, and they have never caused any reaction with me. But one does need to be aware of their potential, which is why I included that statement to my previous post.

Carol, thank you for helping me, I really needed to know since I find is so beautiful. & Nigell, thank you also for helping me out.

Iochroma & GardenGal, thank you for all this information. I agree with winberry that information is much better than complications, as I do have pets to worry about.

Winberry, yes there are drainage holes in every container. It's a must, always.

& Tiffany, I was comparing how silky and smooth #2's leaves are like the Blossfeldiana, but wrote how much thicker #2's leaves are in comparison. Hope that helps in any way to ID it, thank you for your interest

As often as euphorbias are discussed here, ....

One might think so. But when you consider there can be five posts all for pokeweed id on page 1 of these forums, with many back-ups on pages 2-5, maybe the assumption cannot safely be made that people read any other threads than the ones they post. [And sometimes they don't even bother to come back for their own. ;) ]

According to one of my most recent references: Wink and Wyk this Euphorbia is classed as a 1a - the most toxic category - the same as castor bean, oleander, Daphne, and Aconitum.

Most other Euphorbia do not rate higher than 1b, and the poinsettia is a plant that does not warrant even a class 3 (slightly irritating) classification.

Vic, fwiw, I have pets as well. No euphorbia issues with them either :-)

iochroma, if you'd like to post your sources, I'd be happy to review them. I may learn something new. But I do not find anything online or in any of my sources more alarming about this euphorbia species than many others........unless if masquerading as an African bushman, you dipped your arrow into the sap :-) Somehow, I just don't think that is likely to come up too often.

So Just How Toxic Are Euphorbias?

Michael Wink, Ben-Erik Van Wyk : 'Mind Altering and Poisonous Plants of the World' Timber 2008

I also have access to veterinary journals with records of incidents.

"Medicinal Plants of the World" is another excellent book by the same authors.

"Michael Wink is a professor of pharmaceutical biology and a director of
the Institute of Pharmacy and Molecular Biotechnology at the University
of Heidelberg in Germany. He is an authority on secondary metabolites of
plants and their pharmacological effects."

"Ben-Erik van Wyk is a professor of botany at the University of
Johannesburg, South Africa. His scientific field of interest is in plant
classification, ethnobotany, and useful plants."

The elephant bush looks like it is being kept too wet. (Also the potting mix used may be too organic, needing more of a mineral component to be present). Many house plants need watering to fall off markedly in winter, succulent kinds all the more so.
