    'Diamond Mountain' is Proven Winners latest addition to its "Diamond" Euphorbia lineup. They are touting the vigor and size of this one -- bigger blooms and more of them, a bigger plant that can hold its own against other enthusiastic annuals. At 2-3 feet tall & wide, it's almost too big to be a container plant. I could imagine its mounds of foamy blooms working well with wave petunias. If I plant one, I might try digging it up and cutting it back hard (just to make it smaller), then giving it a spot in a sunny window over the winter.
