The History of Jacaranda Trees in Pretoria
The jacaranda tree (Jacaranda mimosifolia), native to South America, has become an iconic symbol of Pretoria, earning the city the nickname "Jacaranda City." These vibrant purple-flowering trees first arrived in Pretoria in 1888 when a traveling nurseryman named Tempelman sold two seedlings to Jacob Daniël (Japie) Celliers at his home, Myrtle Lodge, in Sunnyside. These "parent trees" still stand today at 146 Celliers Street and are credited as the progenitors of many jacarandas in the area. In 1939, the trees were protected with fencing, and a commemorative plaque was unveiled by Mayor Ben Swart on November 8, highlighting their historical significance.
The widespread planting of jacarandas began in earnest around 1898. Celliers obtained a government concession to plant trees in Groenkloof and sourced seeds, including jacarandas, through local businessman James D. Clark. Clark, a florist and nurseryman who arrived in Pretoria from Grahamstown in 1879, played a pivotal role in promoting the trees. Nicknamed "Jacaranda Jim," he donated 200 jacarandas for Pretoria's 51st anniversary on November 16, 1906. Schoolchildren planted many of these along Koch Street (now Bosman Street) and in Arcadia Park, with Mayor J.J. Kirkness and his wife planting two on the corner of Koch and Boom Streets. Despite initial losses, Clark replaced the dead trees, ensuring their establishment.
Clark's legacy extended beyond planting; he became a prominent figure in business and community affairs, serving on boards of financial and welfare organizations. He passed away on January 2, 1956, at age 92, and is buried under a jacaranda in Pretoria's Heroes' Acre, with "Jacaranda Jim" inscribed on his headstone.
Another key figure, Frank Walter Jameson—also dubbed "Jacaranda Jim"—amplified the trees' proliferation. Arriving in Pretoria in 1905 as a technical commissioner for the Transvaal government, he became town engineer in 1909, serving until 1920. Inspired by the Celliers' trees, Jameson established a municipal nursery to propagate jacarandas, chosen for their adaptability to Pretoria's cold winters, which naturally pruned them and reduced maintenance needs. In 1911 alone, he oversaw the planting of 40 miles of jacarandas. The City Council encouraged residents to plant them by offering two trees in exchange for removing root-damaging species that threatened sewage systems.
By Jameson's departure in 1920, over 6,000 jacarandas lined the streets. Planting continued under city policy, reaching 17,000 by 1939 and 25,000 by 1957. Today, estimates suggest Pretoria has about 37,000 street jacarandas, potentially up to 65,000 including outlying areas. Jameson also introduced the trees to Kimberley and Nairobi. He died on February 16, 1956, and is buried in Rebecca Street Cemetery under a stinkwood tree, though he had wished for a jacaranda.
The jacarandas' cultural impact is profound, transforming Pretoria's landscape into a sea of purple blooms each spring. Their introduction and spread reflect a blend of individual passion and municipal planning, turning an exotic import into a defining feature of the city's heritage. No major controversies are noted, but the trees' resilience and beauty continue to draw admiration. I took this photo after a meeting in Brooklyn yesterday.
