Can colorful flowers really grow without direct sunlight?

Prof. Samuel Fitzgerald, Ph.D.Many a gardener wonders if the brightly coloured flowers would bloom if they did not bask in direct sunlight. They would, for nature adapts herself to that which she encounters. Plants like Fuchsias and Begonias seek shady spots and select large leaf surfaces to trap and hold the loose light that is flying around them.
Shade-loving plants have clever strategies. One plant that has learnt to deal with low light conditions is the Toad Lily, which produces unusual spotted flowers. Another plant takes on the challenge of winning over timid pollinators by growing Astilbe flowers, feathery plumes that sway when the tiniest breath of air threatens. The purpose of these bizarre adaptations is clear.
Fuchsia
- Develops larger leaf surfaces to maximize light absorption efficiency
- Produces nectar rich blooms attracting hummingbirds in low light
- Trailing habit positions flowers where light is strongest
Begonia
- Waxy leaf coating reflects available light to neighboring blooms
- Continuous blooming from spring to frost in filtered shade
- Compact growth concentrates energy on flower production
Toad Lily
- Speckled petals create visual contrast in deep shade
- Late summer blooming avoids peak light competition
- Moisture retaining roots support growth in low light
There are many other subtle ways to improve the appearance of tints in shade. A light-colored bloom will come out much clearer against a dark background. Try a silver foliage plant, such as Brunnera, before a dark epimedium, or plant annuals that will filter the sun's rays as they pass through the trees in the early morning. You can tint them as you like.
Season is everything: spring flowers such as Brunnera seize upon the use of early light before the trees join in, summer bloomers such as Fuchsia succeed in the fierce midday heat so long as there is filtered shade, and fall bloomers take advantage of the cooler temperatures. By use of this information the colourful season can be extended.
Proper care will produce flowers even in the home, where sunlight is infrequent. Moist soil is essential, but avoid allowing it to become sour or waterlogged. Keep plants supplied with fertilizer, somewhat heavier than usual, to help compensate for the lack of photosynthesis development. Remember, plants should have good air circulation.
