The 5-foot tall flower has the formal name Amorphophallus titanum. Its smell is described as like that of a rotting body, or sometimes merely like dirty socks.
Michigan State plant biologist Peter Carrington said Wednesday that the corpse flower is expected to bloom next week. It lasts only one or two days.
The plant last bloomed in 2010 and before that in 1995.
The public may see the flower from 10 a.m. to 2 p.m. weekdays and 1-4 p.m. on weekends at the Plant Biology Conservatory.
