It's still overcast here in the PNW, so I thought I'd go out and get some more pictures. This first one is 'Blackout' and its the darkest heuch I own. It takes full sun without crisping up, as long as I keep it watered. However, I think it would be darker in more shade. I've noticed it greening up just a bit as the summer progresses. I love the contrast of the pale flowers against the dark leaves.
