Bright Plants Can Really "Pop" Full Shade Areas
Some of the toughest areas for most gardeners to work with are full shade areas.
Partial shade isn't too bad because some light gets in and can give you more plant choices, such as impatiens and begonias.
A full shade area however, can create a "void" or a "black hole" in your garden that just sits there looking empty even if you have some ferns or other full shade filler plants.
The best way to work around this problem is to use brightly variegated foliage plants, and plants with brilliant flowers.
By doing so, you give the illusion of light in a dark area, which not only makes the area more interesting to look at, but it can also make the area look bigger by adding some depth.
