Shade-loving plants: Fibrous begonias will probably be the most successful. Impatiens may work as well though will not bloom as heavily. There is lots of foliage that would be happy: Lysimachia (creeping jenny), Lamium (dead nettle), fern, Hosta, variegated small leaf ivy, colorful Coleus and Liriope. Cyclamen will be happy in the fall and winter months. You might get some summer bloom out of perennial Campanula and Tradescantia too.
Make Old Feel New Again Have an old planter that doesn’t look as nice as when you purchased it? Bright green sweet potato vine will make the planter look vibrant and refreshed. Plus it will grow over the edge to hide any major dings or cracks.
