I'd be grateful for any suggestions as to what this plant is. It came up in some pots which I had planted with Good King Henry seed for the vege garden.

Not sure whether the seeds was contaminated (it came from an ebay trader) or whether it was the compost I grew them in. But as the latter was made by me and I've never had the plant in the garden before, I doubt it was the compost.

The plant is doing very well and has been growing vigorously since planting out.
