I have alot of shaded garden beds. I have a lily collection that receives filtered light throughout the day and also fancy ferns. Careful with the ferns they will take over if you are not pruning them by the roots every year. Lavendar will stay small and will grow some flowers. Try violets and cala lilies. Enjoy!!!
Calla lily, Clivia, Hellebores, Albutilon, azaleas, camellias, hydrangeas, brunsfelsia (yesterday-today-and tomorrow), campanula, Dicentra (bleeding hearts), heuchera (coral bells), cyclamen, astilbe, Japanese anemone, fuschia and begonias, - just to name a few. Ferns of all kind and lirope (lily turf grasses) are nice green additions for contrast too.
