Older Jacaranda tree in its Spring bloom along 28th Street in San Diego's
historic North Park neighborhood
SPRING IS HERE, SUMMER’S NEAR—For about 11 months a year, the local Jacaranda trees in San Diego look like any other green tree, but come Spring the beautiful Jacaranda explodes into burst of purple/lavender colored blossoms.  This year, the Jac’s bloomed during May and early June.  What’s cool is they can flourish with little or lots of water.  Perfect tree for the rookie gardener.  Unless you don’t mind looking like a wanna be Rose Bowl float, don’t park under the spreading Jacaranda tree because it sap filled blossoms stick to car finishes. 

North Park (Midcity Mesa) area is very clay laden beneath shallow top soil, so Jacaranda roots don't get a chance to dig deep.  Instead, as shown above, this 50 year old "Jac," shows its roots close to the surface.

Common Name: Jacaranda

Origin: Argentina, Brazil Growth Habit: medium to large spreading tree, up to 40-50’ tall and 40-50’ wide

Features/Uses: Jacarandas are among the world’s most spectacular flowering trees with lavender blue, tubular blooms in late spring and early summer. The ferny, compound leaves provide fine-textured shade during the warmer months. They are generally deciduous in the winter. The flattened pods are produced in late summer and fall.

West Coast phenomenon. In the U.S. jacarandas grow better in southern California compared to Florida because of our drier, less humid climate. Although it is a common tree to most Southern California natives, blooming jacarandas astound visiting Easterners who never see trees with such flower color back there.

Bloom Time: Late spring and early summer

Cultural Requirements: Well-drained soils in a warm, sunny site. They are relatively drought and heat tolerant, but tolerate regular watering.
