Answer: You can start by spreading 3-4 inches of organic matter over the entire planting bed and digging it in to a depth of 8-10 inches. Amending the soil will help it drain well and as the compost or aged-manure decomposes it will provide nutrients to the roots of your plants. Some flowering perennials for shade would include Pulmonaria, Tricyrtis, Tiarella, Dicentra and Helleborus. Many hostas have very showy foliage in different sizes, textures, shapes and colorings. Ferns can also add a textural interest for more visual appeal. If you want all season color you might add some of the annual impatiens, lobelia or pansies for continuous flowers. I hope this gives you some ideas.
