Excitement is in the air – and soon, so might be an unforgettable scent.

Wally, the resident Amorphophallus titanum (corpse flower) at the Indiana University Bloomington Biology Building Greenhouse, may be preparing for another rare and spectacular bloom. As this towering tropical plant readies its next display – complete with its infamous rotting-flesh aroma – the Biology Greenhouse invites the community to follow Wally’s journey and support the space he calls home.

IU Biology has launched a dedicated Biology Greenhouse Fund through the IU Foundation. Whether you visit for teaching, research or quiet reflection, your support will help ensure the greenhouse’s long-term vitality.

You can watch Wally grow – and possibly bloom – live via the Wallycam livestream.

Typically, Amorphophallus titanum goes through several leaf cycles before it stores enough energy to flower. Its first bloom can take 8-20 years, and subsequent blooms, if conditions are right, occur every few years. Each bloom lasts only 24 to 36 hours.

Wally is located in Room P of the Biology Building Greenhouse. For visitor details –including hours and a map – see the greenhouse website. Learn more about Wally at go.iu.edu/wally.
