Trifolium trichocephalum?

Hi,

I posted about this plant, that I grew from seed, some time ago but can't find the thread (the Search function doesn't work), so I will post again.  

This was grown as Trifolium trichocephalum (from NARGS seedex) and it has finally bloomed in its 3rd year from seed.  Can anyone who is familiar with it confirm the ID please?  I was counting on finding the old thread, so did not photograph the foliage, but can do so.  Here are the flowers, in any case:

It seems a pleasant enough plant, though too large for the rock garden where I have it.  (I was just waiting to see the flowers in its first bloom, prior to moving it elsewhere in the yard to enjoy.)
