Need med/tall shade plant that blooms in July?

I have a perennial shade border that is currently without blooms except for some impatiens. My gardens generally focus on cut flowers. In this area bellflowers,delphiniums and columbine are finished blooming by the end of June. I have some thalictrum and turtlehead but they won't bloom until August.I did plant some petite delight monardo this year but it will only be about a foot tall at maturity and I need something taller for the background, any ideas for a medium to tall shade perennial that blooms in July?

How about astilbe? Here's a link about it..

I don't know when nictonia blooms, but this silly clownish flower does bright up a dark area and is tall enough. it's white pendulous blooms are cute

Have you thought of Chelone lyonii (Pink Turtlehead)? We're the same Zone altho I'm in the NOrthEast.I got a plant from Shady Oaks this spring and it has been blooming for a month now and will continue til early fall, I understand. They grow to 2-3'x24-30" and tolerate full shade. The color is lovely light and dark pink and makes an attractive shrubby round bush. It's a perennial. I think there is another variety as well. Mine is about a foot high now and will probably grow to full height and width in 1-2 yrs.
