question about identifying perennials

at my workplace, we have acquired a greenhouse full of perennials. however, we are having trouble identifying what they are- at least until they bloom. Is there a resource we can use to identify perennials just by the foliage?

Doug says that a good perennial book (like the Allan Armitage series) is your best bet. Or you can upload pics to this site and you'd be surprised what we can id. We may not be able to id specific varieties without flowers but we can usually do the plant species from a good pic of a leaf
