In this final part of the series of plants that can be grown in containers in the shade, the annual, biennials and bulbs that can be used will be discussed. In previous parts shrubs, trees and perennials have been discussed.
You will note that more shrubs and perennials will grow in deep shade than annuals. You are more limited in what annuals will grow, and so less selection can be made. Most annuals will take light shade but will suffer in heavy shade. Annuals tend to prefer full sun in order to produce their colourful blooms because in the shade, these blooms will look lacklustre. In dark shade begonias, fuchsia and impatiens are preferred for summer display.
In this final part, the annual, biennials and bulbs that do not mind growing in heavy shade will be enclosed. Do not forget you can use a mixture of annuals, perennials, and shrubs in your container display. Use small plants at the front and the taller plants at the back, in a staggered formation.
