In the 1800’s, the gardenesque style arranged exotic plant specimens to show off their full potential. In some cases this was done with a single plant or cluster; at other times brightly colored plants were combined in patterns that resembled carpets, embroidery, and stripes.
When the picturesque style had a resurgence in popularity in the 1800’s, some designers thought that these patterned plantings had gone too far.
One example can be found in the quote above. I think it’s clear where Olmsted stands on this issue.
Nonetheless, gardenesque bedding schemes remain popular. Like our attraction to shiny objects, we can hardly resist the sheer explosion of color and pattern. A few examples above from London's Hyde Park, Chateau de Versailles in France and Keukenhof in the Netherlands continue to draw large numbers of visitors.
