Balboa Park has two thousand jacarandas. They were planted in waves — first for the 1915 Panama-California Exposition, then through the WPA years, then a final round in the late 1950s when the city started taking the park’s landscape budget seriously. Most of them are mature now, between sixty and a hundred and ten years old, and for two weeks every spring they drop a lavender canopy across the Plaza de Panama, El Prado, and the Spreckels Organ Pavilion that does not exist anywhere else in California at this scale.
The picks below are for that window. The peak this year is the week of May 25 — give or take a few days depending on rain. The trees on the east end of El Prado bloom about four days ahead of the western cluster, so if you’re trying to catch peak color in one walk, start at the Bea Evenson Fountain and walk west. The shade is densest under the Casa de Balboa arcades; the open Plaza de Panama is more about the fall of color underfoot than the cover overhead.
A practical note: the rangers sweep the petals from the plazas every morning around 9, which is beautiful in its own way and also means the carpet is thickest before they start. If you want the photograph you want to be there by 7:30.
