Jacarandas in Bloom. 1  One of the most spectacular sights in Johannesburg is when the Jacaranda trees are in bloom during late spring (October-November): 2  These trees, together with bougainvillea in bright pinks and purples, make Joburg look absolutely beautiful at that time of year.
Jacarandas are indigenous to South America, but their history in South Africa starts as early as the 1880s when they were imported from Argentina. In 1888 two trees were planted in a school in Arcadia. Their popularity as a street tree soon took off and they now line many kilometres of streets throughout Pretoria.t is estimated that there are between 40 000 and 70 000 Jacaranda trees in Pretoria-nicknamed the Jacaranda City-which choreograph their spectacular show over an eight week period in late spring each year. There are also almost 100 rare white Jacarandas that can be found in Herbert Baker Street in Groenkloof.
