Hylotelephium 'Matrona'

The enormous flowerhead of a somewhat pot-bound Stonecrop Hylotelephium 'Matrona' (or, to use its more familiar generic name, Sedum 'Matrona') that I discovered yesterday on a 'bargain bench' at a local garden centre, and which I hope to have the opportunity to plant out over the weekend - weather permitting, of course.
