I do love a cardoon, they are fantastic plants. They have the fantastic structural foliage and flower heads that bees just adore. They grow quite tall but do not need staking and just come up and grow year on year.
So I dug it up and I have re-sited it in the pond border where it has more space and more light. I carefully made sure it was at the same depth as it had been previously planted but I wonder how long it sulk for now it has been moved. Peonies are fantastic sulkers, they will sulk at the drop of a hat and moving them makes them stick their bottom lips out so far you can almost trip over them. I will report back.
