I got a deal on a these a few years back, so I have quite a few scattered around. I like the dark stems and they do well for me.
This one is a volunteer seedling from Magnus, (I used to have one behind the yarrow but I gave it to someone with a sunny spot to fill) so it's either Magnus or a fine hybrid--blooming this year so I guess we'll see what the bees made
My favorite white, Fragrant Angel, is just starting to think about thinking about it...
Hot Papaya, moved it from an area with too much pink into a new garden last fall; it seems to be making a go of it
and Summer Sky, moved it last fall, too--from an area with bad soil and too much shade. It seems happier, but it's still a pretty wimpy plant
