Can the succulent on the right side be identified, from this picture, as Euphorbia aeruginosa, or rather just identified as probably, or possibly, E. aeruginosa?. Or does it rather represent a different Euphorbia species. The tallest stem reaches about seven inches.

Thank you.

Looks like aeruginosa to me. Blue-green stems, orange to reddish brown spines and spine shields, tiny yellow flowers.

Looks like Aeruginosa to mee also, but indeed the right one looks more square that the normal ones, this is mine for comparison.

Thanks, Baja and TJOE.
Very nice, TJOE!

Happy crested lactea, 8 inch pot.

Kaktus said: Can someone help me to check if this is E. Unispina?
One seller sells it at half of the market price, plus 2.2 special date campaign, I got it at 1/3 of the market price. When I got such a good bargain, I started to question my own judgement

You will probably not be able to tell definitively until it is more mature. Unispina, venenifica and poissonii all have single spines (or even no spines) so the specific name is of no help in ID. Some variations in leaf shape, number of leaves on mature plants and leaf markings are so variable as to be almost useless.
However when your plant matures and flowers you'll have perspective.
My large plants of venenifica and unispina are leafless but in flower right now.


E. venenifica. Note the bright greenish/yellow glands and slightly greenish/ orange centers.


E. unispina. Nothing remotely green on these flowering bodies.


E. poissonii is not in flower at the moment.

My plants have never flowered even remotely as much. Only one (supposed to be unispina) even has buds at the moment.



On the subject of spines .... On this individual, each node has one main spine, but also 2 accessory spines. A bit like the queen victoria agaves, which have a terminal spine on each leaf but usually also at least a couple of smaller ones in addition. Usually more evident by touch than casual inspection by eye.

These are venenifica and poissonii (sister seedlings)



The mother plant (10" pot) nearly leafless and totally flowerless.



She is entirely spineless. Her offspring are spineless or nearly so (any evidence of spines is more apparent by touch than by sight).

We have received 4 inches of rain this February, and it has been raining nearly every day. This is not ideal for resting Euphorbias but I think the plants in this group do not actually go dormant when they are leafless.

Finally a proliferation on E. globosa, or more precisely 3 of them (regular stems coming off a flower stem). They turn back into flower stems again at the next joint.

Thanks..
@Wildbloomers, they look so beautiful when in blooms, hope mine will flower like that in a year or two..

And I am not aware if they have spines like Baja's photo. Tried to check mine, the so called spines are soft, not hard, and I got a nice photo out of them, they look like a group of stacking owls or chickens.

A bunch of sheep coming out of the stem, maybe?

Some Euphorbia volunteers separated today, with greater or lesser success ... these 2 look like esculenta and a hybrid of mammillaris



These 2 look like an unknown medusa and a hybrid of bupleurifolia (with leaves)



Those plants mostly went into 4" pots.

Any idea if this obesa is a male or female? Tiny flower, just 3 - 4 mm.

Female.

Edit: since I don't have other similar Euphorbia flowers, I pollinated it with E. Knuthii, hope to get some fruit and strange plant out of it.

The bloom of this Monadenium is like asking for a hug.

What a nice plant! Cute blooms!

E. esculenta with good color (unobstructed southerly exposure)

Looks great!

Euphorbia ingens in the public garden. A seedling volunteer, transplanted there a couple of years ago, now branching for the first time (2-3 feet tall). Our latest abundant rainfall will be turbocharging its growth.



One way you can tell it is a seedling (still) is those white freckles on the stem. A mature plant does not have those, a plant started from a cutting will typically not have those (unless it comes from a young seedling of course).

Sister seedlings in bloom here (mammillaris x polygona, boy and girl respectively)





Both are ready to go in the ground soon (3 gallon pots)

During the Hades version of last years' summer, one of the arms on this little unknown died. I left it for a long time and when I snapped it off, just shoved the dried connective end into the soil. Late this winter, I noticed a little arm growing and now there are two on it. Lower left corner in the photo. Blends in with the pronounced red stress color it has compared to the mother plant, but I suppose it will turn green eventually if it continues. Should have stuck it more aligned to the woody appearing area where it was growing on the mother plant, but didn't expect it to live and grow. Hopefully it won't be such a bad summer, but here in February we've reached the mid to upper 80sF with low 90sF predicted this week. Way too warm for this time of year. My face certainly took on a bright red stress color after working outside one afternoon this week. Never thought about sunscreen until the tops of my ears started hurting. Too late then.

Whoever is a fan of Monty Python's Search for the Holy Grail movie, you may also be thinking about the old guy hollering, "I'm not dead yet!"
