I do recall now we had one or two alliums around that part of the garden a few years ago, and the growth of this plant was stunted somewhat by the huge poppy that was growing over it.
Having said that, I have googled tradescantia and some of the images do seem to correspond with my plant. So do the leaves on some of the images.
I'll have to watch and wait.well that's OK. Thanks Bob and Nut for your responses.
