Plants with gold foliage have lots of curb appeal and often prove irresistible. Once they are home, however, they can be a challenge to the gardener. Are you looking to make a statement or create harmony with a team player?
Containers are easy, and flower beds, too. Generally, the more color the better. They are both more forgiving than the broader landscape, where trees and shrubs hold sway. When gold and chartreuse foliage is not used judiciously, all too easily the result is a disjointed collection of freaks rather than a garden.
Rooftops covered with plants go back hundreds, if not thousands, of years. In China there is the roof iris, Iris tectorum, so named because it flourishes on sod. In Northern France and England there is an old rural tradition of growing moss, ferns, and hens-and-chicks (or live-forevers) on the roofs of houses, covered entryways, and out-buildings.
