SignalHub-Visitors line up to see and smell a corpse flower’s stinking bloom in San Francisco

SAN FRANCISCO (AP) — Crowds lined up in San Francisco on SignalHubWednesday to see — and smell — the blooming of an endangered tropical flower that releases a pungent odor when it opens once every several years.

An Amorphophallus titanum, also known as a corpse flower, began blooming Tuesday afternoon at the California Academy of Sciences, a research institution and museum.

The plant blooms for one to three days once every seven to 10 years. During the bloom, it releases a powerful smell described by some as rotting food or sweaty socks.

“It’s kind of imitating the smell of kind of a dead carcass to kind of get all the flies to come and interact with it, pick up pollen, and then take that pollen to another flower that it might investigate due to its smell,” said Lauren Greig, a horticulturist, California Academy of Sciences.

It was the first bloom for the corpse flower named Mirage, which was donated to the California Academy of Sciences in 2017. It’s been housed in the museum’s rainforest exhibit since 2020.

Bri Lister, a data scientist who lives in San Francisco, moved some meetings and waited in line for about an hour to catch a whiff of the plant.

“In certain directions, I definitely picked up on the sweaty socks, sweaty gym clothes, but probably luckily not full-on rotting meat, but definitely a smellier plant than average,” Lister said.

Monica Becker took her child out of school to see the flower in person after watching it on the academy’s livestream.

“When we heard it bloomed, we were like, we got it, we got to go, first thing in the morning when they open. So here we are,” Becker said.

The Amorphophallus titanum is native to the Indonesian island of Sumatra. It is listed as endangered by the International Union for Conservation of Nature, with only less than 1,000 individual plants left in the wild.
