About 5 years ago I planted a euphorbia which obviously dies back each autumn but by June it reaches about 5ft in height and 5 ft in width. I took a stem with leaf and flower to a garden centre where I was told that it was a euphorbia polychroma but I understand that they only grow to about 20" in height. Have you any idea what kind of euphorbia this might be as I would like to repeat it? Many thanks.
