What a great collection of photos! Thanks everyone for sharing.

WOW Lets see what Euphorbias do I have well one is the Euphorbia vigueri capuroniana
on the left side of this photo.

And then there is the Euphorbia tirucalli 'Firestick'

Interesting how the Pachypodium at the right in that first picture is growing toward the light, but the Euphorbia is ramrod-straight. I will take a picture of my vigueri soon to compare, because it's got some great fall colors.

Keep the photos coming!

These 3 plants are the surviving Euphorbias in a garden I planted a few years ago and then mostly abandoned. They get zero water and it has rained 1/4 inch since April.



The second plant is the mother of the third. The father, an anoplia, was the first to be consumed by the bunnies. Their second choice (still slowly being consumed) is a(nother) polygona, a blue plant that apparently tasted worse.

These 3 must taste horrible.

As promised, E. viguieri in all its late fall glory



Compare the colors to this July shot

Well I only have the two Euphorbias right now I might have to add some more next year. It is already December and it is (for me) starting to be really
cold! Of course, I am the real freeze bug in our family so anything under 65 or so is to me cold!

Our low temp for Nov. was 50°F and I'm thinking maybe I should look for some long pants soon.

For those curious to see more Euphorbia photos, as well as read about the plants, I recommend this 2019 book, which was published in South Africa but should be available worldwide, if you look for it.



It's a field guide for the purposes of identification, restricted to one of the world's hotspots, and excluding plants from Madagascar. That said, there's an insane amount of detail aimed at telling one plant from another. Are the spine shields continuous? Do the glands have processes? Are the peduncles persistent? These are the kinds of questions you need to answer in order to get the answer you seek. The plants are arranged in 20 groups based on habit (and certain other features), so you can find the general type of plant you're looking for and then home in on which specific species it may be. Usually the two plants which look most alike are featured on opposite pages so you can compare one to the other most directly.

The plants pictured are mostly not perfect specimens from cultivation, but scrappy and weather-beaten plants from habitat. Which I like as a refreshing reality check. I thought the pictures were incredibly helpful for the purposes of ID, if not general Euphorbical enjoyment.

I started this tree over 10 years ago from a cutting about 2 feet tall. Then a few years ago when it was a little bigger than it is now, I cut every branch off the main stem and trimmed the main stem to about 4-5 feet tall. Basically I just left a stump. What you might call pollarding with other tree species. And now it's incredibly branchy again and will be due for a similar hair cut any time. You have to hack this plant back or it will become a monster.

I see the truth in your comment it"it will become a monster"
My E. ingenis is a monster and it it time for an adjustment.
You have inspired me.
I started mine from a one foot cutting given to me 20 years ago. Now its' 20 feet tall.
Funny how some of the branches grow downward and others are upright.
Now the upper branches are getting top heavy and are starting to droop downward.
I hate to loose the spiral lower branches so I will cut it above those branches.
Maybe some new branches will start out of the lower trunk like yours.


I do love the spiral branching



With the branches being so low it is easy to see the flowers.
I wonder when the seed pods will ripen.

Those spiral branches are indeed really cool.

The fruit goes through color changes from green to yellow to red and eventually brown when it dries out. You can harvest the red fruit (probably even yellow fruit) and leave it in a paper bag, where it can pop without you losing the seed. I like to use fine (nail) scissors and cut at the base of the fruit, avoiding direct contact with any sap that might come out. At some point when it's warm and dry, just put that bag in the sun nearby and you should hear the popcorn going within an hour or two if the fruit is mature.

Wow 🤩 😳 what a magical picture.

I look forward to harvesting the seeds.The color change should make it easy.
I have never had euphorbia seeds before. Are they tiny that need to be planted shallow?

Pretty big seeds, but you don't need to bury them particularly deeply. Some fine pumice or whatever on top is good.

New growth under artificial light

I see all of these pictures of the huge Euphorbias and wonder what I should grow which will stay small!

Two hybrids here...

This noid Euphorbia has been very slow growing for me.
Had it for 10 years with no new growth, but this year it is sprouting.
It always had the extended branch. The new growth is in the middle.
I love the flowers.
Baja, can you tell if it is male or female?

It looks like a female. Three-fold symmetry, parts coming out of the center of the cyathia? Is that E. francoisii? I don't know if that species has sexes. Some Euphorbias make male and female flowers in separate phases, or on separate flowers, but not necessarily on separate individuals. No experience with that plant.

That is a wonderful picture of a Euphorbia! I am trying to deal with the weather right now since I live in Houston, TX and not in Hawaii where I am sure it
is much warmer than the weather here as we are expecting Monday for the temperature to range from 12/24 F and snow showers. I have had to move
all of my cacti and succulents indoors as I have never seen temperatures like these in 38+ years in Houston, TX

Don't let them get too comfortable in there! Stay warm.

Baja, I can see you might think it is an Euphorbia francoisii. The leaf coloring and veins in the leaf look like the Google images of E. franc, but the leaf shape doesn't fit.
Most of the E. francoisii leaf photos have ruffled edges and these leaves are smooth.
The shape of my E. noid is kind of arrowhead.
I saw one like it (arrow shape) in Google images out of the hundreds of photos.

Willinator, in a previous post you mentioned interest in smaller Euphorbias.
This one would be perfect for you as it has grown in a 4 inch pot for 10 years.
I so feel for you and your dilemma of a cold snap.
I came from Wisconsin by way of Tucson Arizona and know what winter is all about
and what blistering summers are too. No Thanks.
Had enough of that and am as happy as a clam here.
My temps are a low of 49F last week to a hot spike last summer of 93F.
Normal is 60 to 80 every day with either rain or shine.

For what it's worth, that Euphorbia is incredibly variable in terms of leaf shape and color. Not saying that's what you have necessarily, but it's known for this variation and selected forms can be relatively rare in cultivation.
