No, Nut. I've moved it once, and split it to give some to my mum (backup plants)
It dies down each year to small tubers a bit like dahlias. The main problem is that is doesn't start to grow until may, so early weeding results in a fork being put through it.
This is a cluster of about 6 plants. I will probably split the larger clump up again this autumn. I seem to have lost the purple version.
