Grown from seed obtained from the SRGC Seed Ex and sown in January last here's ex Polemonium pauciflorum 'Sulphur Trumpets'. I planted out a group of five seedlings that have made a fine, if a little overlarge, clump. I was a little disappointed by the paucity(!) of flowers to the proportion of leaves but I have to say that up close the flowers are beautiful.
I posted these on the SRGC Forum and Trond Hoy advised me that I should plant them in a much leaner soil in order to get more flowers and less leaves.
