LA’s jacaranda trees bloom from late April through mid-June, and the streets with the heaviest canopy, like Stansbury Avenue in Sherman Oaks and Del Mar Boulevard in Pasadena, are the most photogenic and the worst places to leave a car parked overnight. The fallen flowers stain paint on contact, and jacarandas are also an aphid host, so the same trees can drip sticky honeydew long before a single petal falls.
Key Takeaways
- Jacaranda season in LA typically runs late April through mid-June, though an early heat wave can push the start date earlier.
- Stansbury Ave and Dixie Canyon Ave in Sherman Oaks, and Del Mar Blvd and Paloma St in Pasadena, carry some of the densest canopy in the region.
- Fallen flowers stain paint on contact with a tannin-based residue.
- Jacarandas also host aphids, so sticky honeydew can drip onto a parked car weeks before the first bloom opens.
- Fresh residue lifts with a standard wash. Residue that’s cured in the sun for days needs a proper decontamination pass.
Why Does Jacaranda Season Catch LA Drivers Off Guard?
Jacarandas normally flower “from late April to mid-June” across Southern California, according to reporting on the trees’ 2026 bloom cycle. That’s a six to seven week stretch most years, though it isn’t fixed. In 2026, an early March heat wave pushed several LA neighborhoods into bloom weeks ahead of schedule. Because flowering is triggered by temperature rather than tied strictly to the calendar, the “usual” jacaranda season on a street like Del Mar Boulevard isn’t a fixed set of weeks anyone can pencil in a year ahead.
That earlier start matters for anyone parking under one. A tree that blooms in March instead of May is also finished dropping petals earlier, which shifts the entire window a car owner needs to plan around, not just the dates on a tourist map.
Authority Insight: What UC’s Statewide IPM Program Says
The University of California’s Statewide Integrated Pest Management Program, run through UC Agriculture and Natural Resources, lists jacaranda’s bloom window as mid to late spring and names aphids among the pests that commonly affect the tree. That detail matters more than it sounds: aphids don’t produce sap themselves, they feed on it and excrete a sugary waste called honeydew, and that honeydew is what actually drips onto anything parked below, often well before a single flower falls (UC Statewide IPM Program, UC ANR).

Where LA’s Jacaranda Canopy Is Thickest
A handful of LA-area streets carry heavier jacaranda canopy than the rest of the city, dense enough that they’ve become informal pilgrimage spots during bloom season. They’re also, not coincidentally, the streets where a car left parked overnight comes back looking like it drove through a car wash that only sprayed purple.
Stansbury Avenue, Sherman Oaks
Roughly the 3900 to 4200 blocks carry some of the most concentrated jacaranda canopy in the entire San Fernando Valley. The trees here are mature enough that their crowns meet overhead in places, turning the block into a genuine purple tunnel at peak bloom. That same density is exactly what makes overnight parking risky, since a car left under the canopy for more than a day or two collects a visible dusting of fallen blooms. Residents who park here regularly during the season tend to shift to whatever spot gets the least direct canopy coverage.
Dixie Canyon Avenue, Sherman Oaks
Near Valley Vista Boulevard, this stretch adds to Sherman Oaks’ reputation as one of the Valley’s heaviest bloom areas. It’s a quieter residential block than Stansbury, which makes it a favorite for a slower walk through peak bloom without much foot or car traffic. The tradeoff is the same one Stansbury presents: fewer alternative parking spots outside the canopy line, since the trees run nearly the length of the block.

Del Mar Boulevard, Pasadena
Reportedly home to upward of 3,500 jacarandas along its length, this is one of the densest single stretches in the region and arguably the most photographed jacaranda street in LA County. The boulevard’s width means there’s usually more open parking outside direct canopy than on narrower residential blocks, but the sheer volume of trees means fallen petals still accumulate fast on the pavement and any car parked nearby. Visitors driving in specifically to see it should expect competition for the closest spots during peak weeks.
Paloma Street, Pasadena
East of Allen Avenue, this is a well-known secondary bloom corridor near Del Mar Boulevard, quieter and more residential in character. It draws a smaller crowd than Del Mar itself, which makes it a reasonable alternative for anyone who wants the same bloom density without the parking competition. The canopy coverage over the street is still heavy enough that an overnight parked car should expect the same petal buildup as its more famous neighbor.
Los Robles Avenue, San Marino
Home to some genuinely old, oversized specimens, including a jacaranda that’s grown past 50 feet, this is one of the more architecturally striking jacaranda streets in the region. The mature trees here have wider canopies than younger plantings elsewhere, which means a proportionally larger drop zone underneath each one. San Marino’s quieter residential streets also mean fewer commercial car washes nearby, so anyone parking here for an extended visit should plan to clean up sooner rather than later.

North Whittier Drive, Beverly Hills
A dense residential stretch that regularly draws bloom-season visitors on foot, this street sits in one of the more upscale pockets of the jacaranda circuit. The canopy is consistent enough along the block that there’s little advantage to picking one parking spot over another during peak bloom. Given the neighborhood, cars left here tend to be higher-value vehicles, which makes prompt cleanup more of a priority than it might be elsewhere.
Ayres Avenue, Westwood
Close to Beverly Hills and similarly canopy-heavy during peak bloom weeks, Ayres Avenue rounds out the Westside cluster of dense jacaranda streets. It’s less of a destination in its own right than a stop people make while touring the wider area. The residue risk here is identical to its Beverly Hills neighbor: heavy canopy over most parking spots along the block, with little room to dodge it entirely.
Hope and Flower Streets, Downtown LA
A less-expected bloom pocket, these downtown streets carry a surprising concentration of jacarandas among the office towers. Because this area is dominated by weekday commuter parking and structures rather than long-term residential street parking, the practical risk is lower for most drivers, but anyone using street-level parking near these blocks during bloom season should still expect petal buildup by the end of a workday.
Miracle Mile
The stretch along and near Wilshire Boulevard’s museum row gets heavy seasonal bloom coverage, adding a splash of purple to one of LA’s busiest cultural corridors. Street parking here is already competitive given the museums and restaurants in the area, and jacaranda season adds petal cleanup on top of the usual urban grime from Wilshire traffic. It’s one of the few spots on this list where the tree debris competes with ordinary city pollution for what’s actually dulling a parked car’s finish.
Highland Park
Northeast LA adds another dense pocket outside the more commonly cited Westside and Valley spots. The neighborhood’s older, tree-lined residential streets carry a similar canopy density to Sherman Oaks, without drawing quite the same crowds. That relative quiet makes it a good option for residents who want to enjoy the bloom without dealing with visitor traffic, though the parking risk under the canopy is no different from the more famous streets on this list.
Anyone with a car parked on one of these blocks for an extended period during the six-week window should expect visible petal residue by morning, particularly after any wind or rain knocks blooms loose all at once. It’s a different mess than the tree sap or wildfire ash LA drivers deal with the rest of the year, but it calls for the same quick response.

Habits That Protect Your Paint During Bloom Season
Wash off fresh petal residue within a day or two rather than letting it bake in the sun. Skip the leaf blower and dry paper towel approach, both can grind pigment and grit into the clear coat. If a regular parking spot sits under heavy canopy for the season, a ceramic coating makes both honeydew and petal stains noticeably easier to rinse off before they bond to bare paint.
What We See Across Texas, California, and Florida
LA isn’t the only market where a specific tree turns into a seasonal car-care problem. In Texas, it’s cedar pollen coating everything in a fine yellow film every January through March. In Florida, it’s sap and debris from live oaks and palms after a summer storm. California’s version is more visual than most, since jacaranda season is genuinely a tourist draw as well as a maintenance headache, but the underlying lesson is the same in all three states: a tree that’s beautiful for six weeks a year can also be the reason a car needs a wash it wouldn’t otherwise.
Conclusion
LA’s jacaranda season is short, roughly six weeks from late April to mid-June, and genuinely worth seeing on streets like Stansbury Avenue, Del Mar Boulevard, and Los Robles Avenue. It’s also worth parking with eyes open: the mess isn’t only falling flowers, aphid honeydew can be dripping onto a car for weeks before the first bloom ever opens.
FAQs
What months does jacaranda season happen in Los Angeles?
Typically late April through mid-June, though an early heat wave can shift the start date, as it did in March 2026 in several LA neighborhoods.
Which LA street has the most jacaranda trees?
Del Mar Boulevard in Pasadena is among the densest, historically cited at roughly 3,500 trees along its length, alongside Paloma Street in the same city.
Do jacaranda flowers stain car paint?
Yes, fresh petals contain a natural pigment that can leave a stain if left on paint for more than a day or two, especially in direct sun.
Is the sticky residue on my car from jacaranda sap or something else?
Often it’s aphid honeydew, not tree sap. Jacarandas commonly host aphids, and their sugary waste drips onto anything parked below well before or after the flowers themselves fall.
How do I remove jacaranda stains from my car without damaging the paint?
A standard hand wash handles fresh residue. For stains that have cured in the sun for several days, a proper decontamination and polish, rather than dry wiping or scrubbing, avoids adding swirl marks on top of the stain.
