Blooming a once-in-an-agave-lifetime event

A rare blooming plant is reaching new heights at Chicago's Garfield Park Conservatory.

This agave plant is growing so tall, conservatory officials had to remove a glass pane so the plant can continue to grow.

The appearance of a flower is rare because most bloom only once in its life cycle.

The flowering stalk looks like a giant asparagus, which agave plants are related to.
