MSN did an article with the aid of professional landscape designers on what they consider landscaping sins. What struck me to be very strange about this article is the many times, "nature," was used. One of the no-no's was the marching flowers (flowers in a row) because they don't look "natural" because that's not "in" right now.
"Now we plant in mass groupings, more like nature does," says Donovan. "Bunched together, in a bouquet effect, that attracts the eye."
However, Sin # 4 is about having too much.
The upshot? "They'll get this hodgepodge effect," says Donovan, who sees it often. But using lots of colors all over the place "produces chaos," she says. "That's too busy for the eye. It's like wearing too much jewelry." And often all of the color don't complement the home -- one of landscaping's chief goals.
It seems strange to glean elements of nature for some parts, but not for others. It's okay to feign the idea of nature, as long as it is trimmed regularly.
