Any day now, the newest addition to the Titun arum family at the Huntington Library will unfurl into a beautiful, enormous, rotting-stench-of-death inflorescence.

That photo was taken this morning, and it’s grown two inches from yesterday’s measurements. This particular specimen was propagated from the historic 1999 bloom of “Stinky”, the first corpse flower to bloom in California. Here’s a time-lapse video of that bloom:

According to the Huntington, the chemicals responsible for the putrid stench are dimethyl disulfide and dimethyl trisulfide. The odor was previously thought to have been caused by the aptly named putrescine and cadaverine.

The Huntington is featuring special hours for members once the bloom opens. For non-members, they’re open daily from 10-4:30, with the exception of a normal Tuesday closure. However, they stayed open yesterday in anticipation of the bloom, and will likely do the same next week if the bloom-watch is still on.
