Well, clematis and daylilies are problematic. I have one clematis that is/was huge. A Russian strain I think with tiny little blue downward facing tulip shaped flowers. Very simple. Foliage is vibrant chartreuse. Too large and aggressive for the front bed. Just moved it out back to be near a trellis out in the sun. Maybe be a mistake as it tried/succeeded to jump from its former trellis to a tall white lilac and was totally infesting it when I found it. Cut it all out, even broke a limb on the lilac extracting it. The new trellis is close to an apple tree so will have to watch it in future.
Some daylilies work here. It isn't too late to break up a clump and see how they would work out front. They have thrived in my garden for several years now where all others have failed. Our winters have been very very mild the past few years so that might explain their survival. I have a common hardy geranium. My problem with it is that it self seeds terribly. I have them popping up all over the place. I vigorously deadheaded the one remaining one this fall. I was going to move it as it isn't happy where it is so could move it out front. It requires a fence around it as it tends to fall splat when maturing over the summer.
How about Trollius. Also wanted to put some ferns and hosta for filler and different leaf shapes.
