This red and blue column by artist Leen Droppert has stood at a public school at 1972 Nachtegaallaan in Rozenburg since 1. In 2014, the columns ended up in storage because of the demolition of the outdated school building. Since 23 May 2018, the Growth elements van Droppert in the grass again at a new location, the Fazantenpad. This work is very related to the later three columns of Growth forms (1978), which are located next to the GGD in the center of Rotterdam, on the Schiedamsedijk. The rhythm is here in two parts, with slightly more differences in shape.
