Well I am working with my plants here is the picture of my E. mammillaris still in the pot it came in



and we have a picture of the E. bupleurifolia

@Willinator
I hope you post some photos of the E. mammillaris as it grows. Mine was larger when it was purchased.

OK here are some more pictures from today!

1st you have a picture of Euphorbia bupleurifolia

and as requested the latest picture of Euphorbia mammillaris

@Willinator, they both look great. I'm thinking about getting a Euphorbia bupleurifolia as soon as its safe to have it shipped.

OK and here is a picture of one or two other Euphorbias
Here is the Euphorbia vigueri capuroniana


And this is my Euphorbia tirucalli 'Firestick'


Here is the Euphorbia bupleurifolia today!

And here is Euphorbia mammillaris

This "pencil cactus" does not seem to fit the mold of tirucalli. Much fuller, with the smallest/newest stems as big around as my little finger. Much more robust than the four other varieties of tirucalli that I have with more branches spaced closely together. The plant is about 10' tall, the stems stay fuzzy (not losing the scurf and becoming glabrous like tirucalli). And yes, I set it and its 3gal pot down in an old milk crate. I'll never get it up.

Well here are the latest of my pictures:

Here is what the Euphorbia bupleurifoli looks like today

And the Euphorbia mammillaris

then there is a picture of the Euphorbia tirucalli 'Firestick'

Euphorbia stenoclada the green form

Euphorbia 'briar patch'


Euphorbia squarrosa in need of larger pots (they have big taproots)

Euphorbia squarrosa


Three different euphorbia left to right venenifica, poissonii and a hybrid of the two. Note the cold damage on the leaves of the middle plant but not on the others.

The way it branches and how its smaller branches are developed does not give me the sense that this is a straight up tirucalli. I have grown a couple that got between 8 and 10 ft tall so comparable to your plant, and to me at least they did not have a clear change in how they looked, so maybe this is another species or some kind of cultivar/hybrid?

I agree. E. tirucalli cyathia are supposed to be yellow-green, appearing at the tip of branches. Is that your experience, Thijs? My plants don't flower. The branches are a bit more numerous and shorter on the plant in the pictures than the tirucalli that I know. The stems should have pale striations if you look up close. I am not seeing any close matches in my guide book among the pencil-stemmed Euphorbias from southern Africa. Some have reddish cyathia, but none of them have the arborescent growth habit of tirucalli, so I vote hybrid.

Lovely Euphorbias, Wildbloomers. You have some pretty big West African Euphorbias, choice plants.

Thanks for the input Thijs and Baja. I think that the big "pencil " type might be arbuscula. Let me know what you think. The flower color and thickness match but the pictures online aren't nearly as lush as this plant. Hybrid vigor could explain that. I have many more euphorbias including a good sized collection of the Madagascan group. I'll post some pictures on the next rainy day when I have to stay inside.

Euphorbia stenoclada blue form.

My tirucalli 'Firesticks' just bloomed like made and was a crazy bee magnet, which is always surprising to me given how small the flowers are an how there is plenty of other stuff in flower that does not draw nearly as many bees (except for the Palo Verde and Citrus of course).

I have trouble getting a good picture with my cell phone so I will have to take the camera out at some point, but the flowers are definitely in different locations and a different color. also it seems that the 'sticks' have clear joints which Wildbloomers' plant does not appear to have. Anyway, always really cool to see something new.

My collection of Euphorbias has shrunk quite significantly since last summer which was brutal. At the moment I'd spring for one of the really xeric ones that grow big and take full sun here, but they are surprisingly hard to find (I have the name written down somewhere but of course cannot remember it).

I do like the look of the E. stenoclada I may have to see if I can find one at my favorite nurseries.

I also have a question?? I have a Euphorbia bupleurifolia from Planet Desert and now I note there is another Euphorbia listed
called Euphorbia blupleurifolia. Are these two the same plant??

The correct spelling is bupleurifolia (refers to the genus Bupleurum, and the shape of the leaf). For example:



When your plant flowers Will, we can sex it. Should happen when it next leafs out.

Powdery mildew here (I'm assuming) on E. iharanae (only on the leaves):




Not the best shot of the whole plant, just so you can get the general idea. I didn't want to spend a whole lot of time with a fungus-infested plant in my shooting area.



so I tossed the plant, given I have backup and nobody around it seems to be affected. I'm not into treating fungal problems if I can avoid it. I'm into treating by culling as much as possible. Especially given the other ones are still dormant and have not really begun leafing out.

Naturally my neighbors on both sides regularly sniff around the compost pile and take home plants for adoption, and I encourage this behavior, which has made them happy, though anything really contagious (eg. aloe mite) goes in the trash.

That was what I needed So that means I should have an E. bupleurifolia which is what I thought.
I have seen other Euphorbias that I really like the look of and I might have to go looking for!

One is the Euphorbia submammillaris
Another might just be the Euphorbia anoplia "Tanzanian Zipper Plant"
Or possiby the Euphorbia monstrose
Or the Euphorbia milii

Another NOID euphorbia.
There are no spines on the old leaf stipules

Flower spikes are branched and have paired opposite leaflets. The flowers are bisexual

The leaves are 8-10" long

Plant is self fertile

Hopefully someone will recognize this

Euphorbia geroldii
Looks like a millii but has glossy leaves and no thorns. It's a scrambling plant that tries to grow upright but ends up with weeping stems due to the weight.




Euphorbia bougheyi

Euphorbia perrieri

This was labeled lambii but I have doubts now that it's flowering. Probably punicea.
