Does anyone know this Hypericum? It was growing in one of my troughs but died. A seedling appeared in the garden this year.

Nice form in the third photo! I'll be interested to see what people think as far as I.D.

I don't know it, but jolly nice Mark. I hope you can replace it.

Carlo, the third photo should be the same as the one in the crevice trough
Lesley, the third shows the seedling which is still alive
I'll look for seeds tomorrow

Mark, it looks like a hairy plant, so it could be H. tomentosum from the S. Europe.

Initially I thought it might be H. tomentosum, but then the habit in flower doesn't match what I grow under that name, although I admit that I have never tried to verify that what I'm growing is true tomentosum. I find Hypericum to be another difficult genus to key, as there are species throughout the globe, and no good single reference (that I know of) on the genus.
My "H. tomentosum" starts out with basal shoots, rather fuzzy and whitish-green, but these grow upright to 1-2' (30-60 cm) and have very small flowers, Mark's plant looks like a much nicer rock garden worthy Hypericum.
Reginald Farrer in The English Rock Garden writes about H. tomentosum: "a woody plant with many flopping stalks clothed in oval foliage that in its turn is clothed with fluffy down or wool. It is not a common speciesm being found here and there in the warmer parts of South and Central Spain; with two varieties, H. t. dissitiflorum and H. t. intermedium."
H. tomentosum might be described compartively against a related new species here, but this is a "pay for publictaion" link.

And found a few photo links of tomentosum, again, I can't vouch for species ID authenticity, but the following two look similar to what I grow. The flowers are rather small.
