Perhaps Euphorbia cyparissias.

Here is a link that might be useful:

That is exactly what it looks like! So does anyone know if this is considered a flower, wild flower or a noxious weed? There seems to be a lot of it around, especially in damp areas of the property. I think it's so pretty!

I have the variety 'Fens Ruby' in an out of the way spot in my garden, it's duking it out with some Ajuga. Although you will find these for sale BEWARE they are invasive little devils. 'Fens Ruby is planted in the edge of a gravel path, it has crept into a patch of Ajuga, the combination is quite pretty so it stays. So far I haven't had a problem keeping this one under control, I just rip out what I don't want.
On the other hand I bought another variety with reddish tips on the new growth. I can't remember the name has wols or wool or something similar sounding in the variety name. This one has been a real pain in the ... it's in my perennial bed and I have been trying to get rid of it for the last 3 years.
