After the Rose Parade, most of the flowers from the floats are removed and either composted, recycled, or donated, rather than simply being thrown in the trash.

Main things that happen to the flowers

  • Composted into mulch :
    The primary fate of the used float flowers is composting. Volunteers or float crews strip the blooms and other plant materials off the floats, and this organic material is sent to local recycling or composting facilities, where it is turned into mulch and soil amendments that can help grow new plants and flowers.
  • Part of a longer cleanup :
    Deconstruction is not instant; removing thousands of flowers can take days or even weeks in float barns, and it gets pretty smelly as the flowers wilt before being fully processed.

What about unused flowers?

  • Collected and made into bouquets :
    Flowers that were ordered for floats but never used—like extra roses, carnations, and other stems—are often rescued by local volunteer groups instead of going straight to the dumpster. These are gathered in buckets, then bundled into fresh bouquets.
  • Donated to the community :
    Those bouquets are loaded into trucks and delivered to community hubs such as churches, hospitals, senior facilities, and other local organizations, spreading a little post‑parade cheer around Pasadena and nearby cities.

What happens to the rest of the float?

  • Frames and structure reused or recycled :
    After flowers are removed, float builders disassemble the structures: wood framing can be reused or recycled, and metal elements are also recovered and recycled or used again in future floats or projects.
  • Natural materials fully stripped :
    Crews take off all living material—flowers, leaves, seeds, bark—so that only the underlying structure remains, ensuring almost everything organic ends up as compost rather than landfill waste.

TL;DR: If you’ve ever wondered “what do they do with the flowers after the Rose Parade?” —they’re mostly composted into mulch, with many unused blooms rescued, turned into bouquets, and donated around the community, while the remaining float materials are carefully recycled.
