Euphorbia purchased as absynnica but still unsure of identity. It is a very large plant, well over 8" diameter.

the plant above was over 5' tall this spring so I cut the top 20" off and rooted it. This photo is of the new branches/pups growing out of the cut site of the primary plant.

Euphorbia sekukuniensis. Same plant as above after it was cut back. This species is an excellent example of how some cuttings will simply not produce a normal plant once rooted. The rooted pieces just continue growing as a branch. Some Euphorbias, but not this one, can have a cutting taken and rooted, then have another cutting made of the newly established plant and rooted with a resulting normal growth habit. This is often referred to as the two cut method.

Euphorbia scitula. Rooted cutting. This photo is from last fall. During the winter this plant died back except for two short distal branches. I have spent most of the summer trying to reroot the two pieces.

Purchased as Euphorbia ammak. There were two rooted cuttings in the pot. This one that was branched and one that still, after three years is just growing straight up - over 4 foot now.

I don't even try to capture the seeds as they would be unidentifiable hybrids in nearly every case and catching the little devils is tricky at best. The voles also seem to be doing an excellent job of eating ripe seed capsules.
The collection all goes back into a large south facing sunroom to spend mid October to early May. I have a fan moving the air the entire time and a heater ensure the temperature does not drop below 52 degrees. During this time the plants will only be watered three or four times using water collected from a dehumidifier over the summer months. Before moving them inside, I treat the entire collection with a systemic pesticide. Over an average winter I will only lose 3-5 plants out of over 300.

Wow, you have quite the Euphorbia collection! Actually quite the opposite of what I've sen before. You have a lot of the larger species that some people don't care about. Myself included, until I saw how nice they can actually look when taken care of! I guess you see them in bad/okay shape and don't really get the idea of it.
You also seem to have some quite rare specimens in there, some I haven't even heard of before. clivicola, tortillis, atroviridis, colliculina, juglans are some of my favourites.
I'm also surprised you haven't gotten any of the compact Madagascar varieties!
What do you do with the seed? I love planting Euphorbia seed when I get the chance.
What Malagasy varieties were you referring to? I don't really keep any that have long term leaves or woody varieties.
Many of the Euphorbias I have will cross pollinate, so the seeds that form are more than likely hybrids. This, coupled with the tricky nature of capturing the ripe seeds, keeps me from spending any time trying to cultivate them.
The rest of the collection includes Hoodia, Senecio, Pachypodium, Adenium, Alluaudia, assorted cacti, Monadenium and a few Crassula. I hope to post photos of these plants as time permits this autumn and winter.

I meant the classic dwarf varieties such as francoisii, decaryii, capsaintmariensis etc. Seems like most Euphorbia fans have at least a few of those.
Do you ever have them germinate from the ground or other pots? I have a friend who has a lot more than me and he gets little obesa and meloformis seedlings all the time. I have a leuconeura that I get a lot of. I find the idea of strange hybrids interesting but maybe that's not you. I'd collected seed from my Monadenium by tying a small section of panty-hose over top the capsules until they burst and then collecting them. I'm hoping to get some seedlings over winter. I also collected some capsules which were clearly drying (going yellow/brown) and just removed them from the plant and put them in a small container until they burst. Pretty sure they will be viable. Actually over the summer I collected some when I was in San Francisco while they were still green. I'm not sure those one germinated or not (I had a big mix).
I grew Euphorbia neohumbertii, E. pachypoides and E. viguieri v. capuroniana at one time but ended up donating them to the local Botanic Gardens when the were about 8" each. They wanted to leaf out too early in the spring and were very easily sunburned even after careful acclimation to the sun. They are much happier at the gardens and I ended up with room for three plants I liked better.
From time to time I get volunteer euphorbia plants in my pots. More often than not they are E. knuthii or E. flanaganii hybrids. If I see a seedling starting in one of my pots I usually weed it out and chuck it.
Hoodia seems to be my most common volunteer seedling type. I usually have five or more adult Hoodia species plants and they readily cross pollinate. They have the odd habit of delaying seed pod formation from late summer pollination events. The plants will suddenly start forming seed pods in early spring. Each pair of seed horns will release 50 or more tufted seeds that readily germinate wherever they land. I don't believe that these seeds are viable for more than a month or two. I had so many small hoodies growing at the end of this growing season that I will likely remove them from the pots they germinated in and give them their own pots in the spring. Unfortunately they will be hybrids but most Hoodia plants look the same - it's the flowers that differ. They grow fast and just seem to exhaust themselves after a few years. I have yet to see one live longer than 6 years.
Anacampseros rufescens Is another plant that will seed itself in every pot within 10 feet of itself.
