The site was previously occupied by a gas station, operated by Armand Ferland, father of the celebrated lyricist-composer-singer Jean-Pierre Ferland. That is why the plaza is named after one of his songs, whose title translates as "flowers in asphalt".

In addition to containing rainwater collection facilities, the unique design includes fine mist from jets installed among river rocks, a variety of plants, street furniture. An artwork by the En temps et lieu studio is suspended above the plaza.
