Hope springs eternal! Siberian Bugloss (Brunnera macrophylia) should do fine in the garden here. It's a tough plant that spreads happily in shady areas - in theory. I've tried it several spots and it didn't take to any of them. Then a friend gave me a clump last year and it seems to be doing well so when I saw these two in coir pots at my local garden centre I couldn't resist.
 A few weeks from now I will post a photo of the lovely sky blue Forget-me-not flowers that B. macrophylia puts out in spring- I hope!
