eternal euphorbia

I had to look back in my own blogposts to see how long I've been playing with this sprig of euphorbia. It seems I first put it in a vase on the windowsill on Dec. 18. As its lower leaves have faded, I've kept shortening it and shortening it until today, it's quite short, but looks fresh as can be. I'm astonished by how long this one stem has lasted--and it looks nowhere near death even now.
