Shade Tolerant Plants with Large Flowers
I have a garden that once received full sun and produced beautiful roses. As my trees have grown the garden has become shaded. Now I am looking for some tall shade tolerant plants with large flowers.
Consider a combination of perennials that provide a variety of bloom throughout the summer. Astilbes come in a variety of colors, heights, and summer bloom times.
The plume type flowers put on quite a show. Snakeroot and Meadow Rue are tall plants that flower in the shade. Black snakeroot (Actaea racemosa formerly Cimicifuga racemosa) can reach heights of 4 to 7 feet and blooms in mid summer. The Autumn snakeroot (Actaea formerly Cimicifuga ramosa or simplex) looks similar but flowers in the fall. Meadow Rue (Thalictrum) is a summer bloomer that grows 3 to 5 feet tall. Pick a hardy cultivar with the size and flower color of choice.
A shorter long flowering perennial is Corydalis lutea. This twelve inch high plant is covered with yellow flowers from June to frost. It does reseed so you will need to do a bit of weeding to keep it in line.
