Rosie the corpse plant emerged from dormancy in late March.

One of the world's rarest, largest and foulest flowers will bloom Thursday night at the Tucson Botanical Gardens. It's been a long time coming.

Amorphophallus titanum, better known as the corpse flower for its signature rotting-carcass odor, can take 7-10 years or longer to bloom.

Now, at long last, the blessed day is upon Rosie, as the garden calls its 3-foot-tall plant.

Corpse flowers, which are threatened by habitat loss in their native Sumatra, bloom for 24-36 hours and produce small reddish fruit.

Those who cannot make it to Tucson, or who would like to spare their noses the experience, can view a livestream on YouTube.
