Philadelphia's cherry blossoms are on track to reach peak bloom from April 5-8.
Why it matters: Cue weekend crowds in Fairmount Park vying for the best selfie content and picnic spots among flowering trees.
State of play: Philly's annual Cherry Blossom Festival's main event — Sakura Weekend — runs April 5-6, lining up with the peak-bloom forecast.
The intrigue: Blossoms could come sooner, if forecasts for above-average temperatures pan out for the rest of March, Vince Marrocco, director of horticulture at Morris Arboretum and Gardens, tells Axios.
This spring's peak season in Philly is slightly later than last year's, Marrocco said.
- That's because Philly saw a typical winter this year with a string of cold snaps.
Threat level: With our warming springs, the effects of climate change are a threat to Philly's beloved blossoms.
- Rising temps and more precipitation over the past century can weaken them and make them more susceptible to disease.
Last summer's heat waves and drought may affect blooms this year, including the potential for reduced flowering.
- For affected trees, "they'll still bloom, but they won't bloom as much," Marrocco noted.
How it works: Once those buds pop, expect flowers to last up to two weeks, depending on the weather.
Nearby blooms: D.C.'s cherry blossoms are slated to hit peak bloom March 28-31.
1 cool thing: Philly's cherry blossoms don't flower at the same time.
- The city boasts a variety of cherry blossom species throughout the city, with some flowering earlier or later than others.
- For example: Some trees at Morris Arboretum and Gardens may have already started to pop.
What they're saying: "We have so many species of cherries that we get a really long season of bloom," Marrocco said.
What's next: Philly's on track to add 250 new cherry blossom trees by 2026 for the nation's semiquincentennial anniversary.
- A ceremonial tree planting for the project, which began in 2024, is set for Wednesday at the Horticultural Center in Fairmount Park.
