False alarm: The corpse flower is now predicted to bloom Saturday afternoon, keeping its infamous decaying-meat stench away from enthusiasts for another day. Officials revised the timing after crowds gathered at the UCSC Arboretum on Friday evening, only to witness the plant still in its scrunched-up state.

Update: Corpse flower enthusiasts will have to wait a bit longer for an actual bloom — Saturday afternoon or later — according to Arboretum officials. “The flower is not progressing,” the organization said in an Instagram post Friday night. "... with this trickster, we aren’t sure about anything!” Check back for updates throughout the weekend.

Previous update:

The corpse flower at the UC Santa Cruz Arboretum is expected to fully bloom Friday night, and staff said as of early Friday evening, it was already emitting its horrendous stench.

UCSC greenhouse staff have been tending to the titan arum (Amorphophallus titanum) on the campus since 2013. This is the first time this particular flower will bloom. Following this event, it will now be able to bloom every three to four years.

When the flower blooms, it emits a stench that arboretum Director Martin Quigley describes as a “dead cow in your living room with a layer of s--- and then some vomit and dead fish.” The stench attracts pollinators like flies and beetles that are seeking to lay their eggs on decaying meat. The flower blooms for about 24 hours and then begins to collapse.

Quigley said the arboretum would stay open Friday night until 11 p.m. to allow the public to experience the bloom.

He recommended people bring flashlights and good walking shoes. The center has a very small parking lot, so if possible, walk, ride a bike or take a bus.

The arboretum first started posting on its Instagram about the plant on July 14. On July 16, it said it expected the corpse flower “to fully bloom in the coming days.” Fast-forward two weeks and hundreds of frantic and excited Instagram and Facebook comments later, and nature prevails.

Jim Velzy and Sylvia Childress, the former and current directors of the UCSC Greenhouses, respectively, have been maintaining it in the greenhouse facilities. The plant, native to Sumatra, Indonesia, needs a tropical environment in order to thrive.

Each year since it started germinating, the corpse flower has grown a single large leaf that resembles a tree. It can only reach a blooming stage when the underground stem, called a corm, stores sufficient energy and grows to about 35 pounds.
