The Ruth Cardoso Orchidarium, located within São Paulo's Villa-Lobos Park, has officially reopened its doors to the public after a decade-long closure that began in 2015. The facility, dedicated to the cultivation and exhibition of orchids, underwent an extensive renovation process costing around R$2 million. This investment focused on the structural rehabilitation, the preservation of the original architectural design by architect Décio Tozzi, and a renewed emphasis on its educational and environmental functions.

Initially inaugurated in 2010, the Orchidarium is designed to resemble a traditional 'oca' and is home to 27 species of orchids, including native, exotic, and ornamental hybrids. The surrounding landscape features over 50 species of native and arboreal plants, such as the Pau-brasil and various bromeliads and ferns, contributing to the locale's biodiversity. Among the highlights of the orchid collection are the Cattleya labiata, known as the "queen of orchids," and Laelia purpurata, the "queen of the southern orchids," alongside varieties originating from Asia, illustrating the global diversity of orchid species represented in the space.

The reopening of the Orchidarium not only provides a recreational space for visitors but also aims to enhance public understanding of biodiversity and environmental sustainability. It represents a significant investment in cultural and educational resources within São Paulo, encouraging community engagement with nature. The emphasis on maintaining the park’s environmental role reflects broader concerns for conservation and the importance of preserving native flora, making this not just a reopening, but a revitalization of ecological awareness in the region.
