Darmera peltata is a big fave with me - I dont use it as a pond marginal as I find it too rampant, but in heavy soil in the open garden its a fine addition and easy to keep on top of whe you don't have to wade to get to it. Very similar feel to gunnera, but ardy and not so ridiculously huge. Also foliage turns fiery in autumn.
Heuchera 'lime rickey' or 'key lime pie'. Glorious zingy green in shade, ghastly sick yellow in sun. Evergreen and very very tough. Also dead easy to propagate from the teeniest bits. Lovely with euphorbias, dicentras and any of your other typical spring woodlanders. I usually snip the flowers off so I can see wot's behind better.
Bergenia cordifolia. I cant grow hostas - they're eaten before they're fully up in my shady garden of dry stone walls (snail heaven) - so I use bergenia as an evergreen alternative. If you take off old leaves in early spring the fresh growth is lovely and some have gorgeous deep purply flowers as a bonus, as well as the standard pink and white. Luscious in big swathes, with taller, finer-leaved things behind.
Could go on forever. And don't get me started on shrubs, Wintergreen. We'd only make each other worse...
