Johannesburg is home to the world's largest man-made forest. There are at least 49 species of Jacaranda, most of them native to South America (particularly in Uruguay, Brazil, Peru & Argentina), and the Caribbean basin. The tropical trees were imported to South Africa more than one hundred years ago. October is the month when the flowers of thousands of Jacaranda trees are in full blossom. This spectacular tree tunnel is located either in Johannesburg or Pretoria, the Jacaranda City where 70,000+ Jacarandas add vivid splashes of purple-blue to the urban landscape.
