I know the subject of this hybrid has been beat to death on Alpine-L (I think)...The plant is widely available. I post this picture as a caveat: it is dazzling, but the plant must grow in rich, moist, humusy soil to perform like this. In my shady rock garden where most Heuchera and many auricula penstemons thrive (and all manner of daphnes) this sulked. This is in Sandy Snyder's fabulous garden, on the north side of her house: there is no tree root competition, and lots of Sanguinaria canadensis 'Multiplex', Cyclamen europaeum, wild gingers and suchlike thriving. This blooms forever: I really must prepare a good spot and get it again!
