A Once‑in‑a‑Lifetime Agave Bloom

An arid, desert-dwelling succulent in West Lafayette, Indiana. A plant famous for a liquor distilled from its core. And a bloom that only comes once a lifetime.

Mary Alice Webb, professor emerita of botany and plant pathology, researched how plants take up calcium and other minerals. After a trip to Mexico in the 90s, she returned with her a pot of small, sharp, blue succulents to show her students: Agave tequilana. This giant plant has long been important to indigenous Mexicans and is known around the world for the tequila made from its stored sugars.

Over the past three decades, this agave plant has overtaken its space in Purdue University’s Lilly Life Sciences Range. The plant only blooms once in its lifetime — a phenomenon followed by seeds and new pups of the mother plant as it slowly wilts away. And that “death bloom” began in late April 2026.

The flowering spike can get as tall as a telephone pole and grows 6-8 inches every day. As a relative to asparagus, the structure looks strikingly similar to the vegetable. While its difficult to tell how long the bloom will last, you have the opportunity to watch it online live directly from the greenhouse.

You can also visit us on campus for a greenhouse tour or open house, where the glass panels above have been removed to let the flower reach its full height. Keep an eye out for more pictures, events and a timelapse or two!

Dozens of professors and hundreds of students have watched this plant grow in the Lilly Life Sciences Range, taken selfies in front of its great blue leaves and inevitably pricked themselves on the tips. Seeing it bloom now is a powerful reminder of time, patience and learning across generations.
