Perennial flower suggestions?

I am putting a new flower bed in my backyard -- it will be around 60 feet long and only about 2 wide -- I will be using gravel instead of mulch -- it will be full sun to part shade running along a privacy fence. I am looking for ideas of perennials that are tall and not terrible bushy (I'd like to keep them confined in the 2 foot space). I like tall flowers as well as decorative grass. I live in Northern Kentcky, zone 6.

Any suggestions will be much appreciated thanks!

Go to this site linked below, even if you dont buy there, you can see what the plants will look like.

Daffodils, Iris, hollyhock, foxglove, Grass- Pampas, just to name a few, check out the bulbs section and the perrenials section.
