True blue: Delphiniums, Gentiana asclepiada(not all), many alpine Gentianas, Brunnera, Scilla sibirica, Bellevalia forniculata, Commelina(for very mild climates), Omphalodes verna,Centaurea triumfetti,some Corydalis. There are some rare blue Penstemons, but nearly all are ungrowable here. Plants approaching true blue: some Tradescantias. Iris sibirica Big Blue has a true blue nerve in the middle of the falls. Have never seen a blue Campanula, and I had really many. Amsonias are pastel blue. None of Anemone nemorosa clones is true blue(I had them all).

Now that mine has bloomed, I'll have to say the blooms were not very impressive. They opened late, sometime in September, were small and not a bright color. However, mine don't get full sun, so that is probably a big factor. I have some eupatoriam 'chocolate' that also bloomed very late in the same bed. I will have to move some kalimeris in front of the joepye to get more bang for the buck. I like the idea of trying some indoors. Never thought of that.

Wow. Thanks so much for the info everyone! I'm laughing that "Blue Falls" and "The Blues" are the same - the guy at the nursery said that Blue Falls is a new and rare cultivar that nobody else in the area would have. I also recently planted a weeping white spruce that was supposed to top out at at 10 feet so I'm really glad you gave me that growth rate link - I may have to relocate it now while it's small. I had no idea that they would keep on growing forever - I really wish they had specified that when I was shopping - I may have to rethink where I am planting some of these. Do they continue to grow wider forever also? For the Blue Falls - if I want it to grow upwards do I need to stake it? They said it would grow that way naturally but as I google image search for it now it shows a lot of them laying down. Should I just find a really long stick and tie it to the trunk? Thanks again so much - I'm learning much more on this thread than I did after several days of visiting nurseries!
