The Missouri Botanical Garden has drawn crowds wanting to revel in the smell of the aptly named corpse flower, the amorphophallus titanum, since it first bloomed there in 2012. Its offensive odor has been likened to rotting garbage, dirty diapers and, yes… a dead body. Horticulturist Emily Colletti has cared for the garden's collection of corpse flowers for 21 years. She shared what makes the odoriferous plants happy, and how she can predict when this year’s blooming flower Octavia will dazzle and stink.
