Amazon Spheres corpse flower

Amazon welcomed visitors into its headquarters over the weekend to see a rare corpse flower named Morticia in bloom.

The 6-foot-tall plant, which is technically called a "titan arum," sits in the rainforest inside of the Spheres on Amazon's Seattle campus. The Spheres opened earlier this year, and they're intended to serve as a relaxing place for employees. But Amazon let visitors into the dome-shaped buildings over the weekend to witness an event that only happens once every seven years (at least) for the corpse flower.

The corpse flower's name comes from the plant's dank smell, reminiscent of rotting flesh. But that didn't stop thousands of visitors who lined up to get a closer look of the plant's bloom, which lasts only two days.

Watch the plant over time reach its full bloom inside Amazon's rainforest:

The plant is housed inside the Amazon Spheres, a series of glass domes that are part of the the company's Seattle headquarters.

Business Insider's Avery Hartmans visited the Spheres in downtown Seattle last month. The glass dome-shaped Spheres were designed as a relaxing communal place for Amazon employees to work and collaborate. The Spheres officially opened earlier this year right next to Amazon's existing headquarters, whose construction cost a cool $4 billion.

Besides the indoor rainforest where the corpse flower is located, the area also features lawn games and a dog park.
