Euphorbia cyparissias
It reproduces by seeds and also by the very well developed underground roots. It usually has a height of 10 – 80 cm. Its petal-like bracts are usually green-yellow, maturing to purple or red from May to August. Cypress Spurge grows a fruit that, when mature, explodes to spread seeds up to 5 m. However the plant also reproduces through lateral root buds which allows it to spread quick and densely. It can be easily identified by its leaves, which are small and linear (they have a length of 2–4 cm and a width of 1–2 mm).
It is native to Europe. Cypress Spurge thrives in open, disturbed areas rather than forests or highly cultivated soil.
As I told you and before euphorbias are quite various. You are comparing them by the tallness but that isn't quite right, because how big one plant will grow depends on the plant hormones, how much water it gets, how much sun it needs and so on and so on. Yes, the young stems are without branches, but when the flowers on the central flower stalk fade away (you know that the orange leaves aren't part of the blossom, right) the leaves get old and the plant gets branchy with sterile or new-flowers-bearing stems. If why you see some young and old euphorbias in the same time is bothering you, that is because some started developing more earlier than others, or some are bigger than others and they need more time to fully grow.
If that doesn't answer you, there is a huge chance that I haven't understood the question. :D :D :D
Old...hm I mean that a bit not logical, here is very warm and it raining every second day and this plants are small while I have a pic will post it maybe to see the size of our gigantic sun spurge- bigger than my open hand and about 1,5 m tall while I have spotted this few weeks ago http://www.projectnoah.org/spottings/214... inlands in Zagreb where is not so sunny and definitely not so warm, and they look very different. Btw I haven't spotted a single one here on the coast that is not red-yellow color and that hasn't this branches.
I have huge doubts that this in the link is really cyparissias, or at least the wild type, could be some cultivar, don't know. (Edit: Nope, it's different species, post it as a comment in the link)
The orange color in yours shows that the flower stalk is old already, and when this happen it gets branchy. :)

http://www.projectnoah.org/spottings/165... This is significantly different than my spotting, you see: the flower get out straight from the steam, mine has few branches under.
the problem is that cyparissias grows and a single-branched plant and then it splits when it has this green flowers, but as you can see, my plant is splitting before in 5 branches and than over that are going flowers....and plus dont know how explain this coloration. http://www.ct-botanical-society.org/gall...
