Impatiens are good flowers for shade, but they are summer bedding only.

Azaleas and rhododendrons are woodland shrubs, although they only bloom once a year, camelias too, and hellebores also can cope with shade.

ferns, bluebells, rhododendron, bleeding heart, viola, some geraniums, anenome, pachysandra, hellebore, some hostas, bergenia, lambs tails,ivy: we have all of these growing in a very shady area of our garden.
