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.



Hi Gilbert and welcome to GoY. We need a photo to give an i.d. on your euphorbia, or, preferably, a close up and and photo of the whole plant.

It sounds more like euphorbia characias

Polychroma has shorter, broader leaves than a characias, but that may just mean that the nurseryman was more mistaken.

How about Euphorbia palustris? Looks like polychroma but reaches five foot.

I have photos of this species at Wallington Hall in Northumberland. Spectacular hardy perennial much underused!

The trouble is, people panic when they realise it gets tall.

How do I say thanks?
