what kinds of different flowers will grow good in a raised flower bed ?

what kinds of different flowers will grow good in a raised flower bed that spends approx 3/4 of the day in the shade? i live in western Montana.

You could try:

Pansies ++
Bergenia ++
Ferns
Sutera
Impatiens
Alonsoa
Chattham Island Forget Me Nots ++
Clivea
Cinneraria ++
Fuschia ++
Ornamental Kale ++
Aucuba

There are some ideas. But it totally depends on your climate. I believe Montana gets very freezing winters? The best thing to do would be to ask for advice at your local garden centre.
