Common name: Crown of Thorns, Christ Plant, Siamese Lucky Plant
With those big glossy leaves it looks tropical. Is it? I have one euphorbia bet the leaves aren't like this, they are small and have a tinge of orange to them.
This is not my plant; I took the photo while visiting a friend a couple of weeks ago. I don't remember the leaves looking as glossy as they do in the photo. I do know he takes it in for the winter. He keeps promising a start for me....
Well, the leaves are wet - you can see in the picture that there are droplets of water on the leaves and bracts. It is a beautiful green that came out in the picture, but the glossy texture seems to be from the water; it's even pooling in some of the leaves. Also, I've seen euphorbia milii (C. of thorns) that have dark green, smooth almost strappy leaves, and others that have shorter, mottled leaves with mixed colorings of green, grey, orange, and purplish-brown. Some of this may be due to variance in light levels or sun scorch, but most of this coloring is just their natural foliage; it's all about the plethora of varieties available. Some are pretty ugly but facinating in their own way. Gorgeous shot by the way.
