As the best known place in the city, the image of greenhouse is used from many manifestations: since 2008, the park lights are turned off by one hour as a way to join the Earth Hour (an global event organized by World Wide Fund for Nature - WWF - held on the last Saturday of March annually); every year, in October, the greenhouse is illuminated with pink, to support the "Breast Cancer Awareness Month"; in December, an Christmas decoration is made, as part of the "Christmas of Light". And a thousand days to the World Cup in Brazil (2014), between 16 and 23 September 2011 was made an tribute with the light colors of the flags of each country that has won the championship: Brazil, Italy, Germany, Uruguay, Argentina, England, France and Spain. At the same year Curitiba became part of the cities engaged in the "Decade of Action for Road Safety", by United Nations; the yellow color, that in traffic means "attention", lighted the greenhouse.
