One of the conservatory's crown jewels -- an Amorphophallus titanium -- is sporting one of its rare flowers, which is expected to open fully on Tuesday.
The "corpse flower" is almost extinct in the wild and is a 10-foot-tall structure that smells like rotting flesh, according to conservatory officials.
The conservatory's titanium, nicknamed "Terra the Titan," last flowered in 2005.
