Need to know what the flowers are like, so if you have a photo of those, that'd be good. It smacks of Euphorbia to me... but knowing what the flowers are like will confirm/deny that.

Type 'Euphorbia Humpty Dumpty' into Google, and select images, to see if the flowers are similar to your plant...

That looks like a Euphorbia, not sure which one. What are the flowers like?
Or on second thoughts, could it be a perennial wallflower?
