The rare corpse flower is now in bloom at Longwood Gardens in Kennett Square, Chester County.
It blooms rare, but when it does the flower gives off a foul smell that lasts between 24 to 48 hours.
Tickets to see the flower sold out Tuesday and are limited for Wednesday.
Visitors online said they waited at least three to four hours to see the smelly titan arum.
And one couple even got engaged in front of it.
Longwood Gardens is streaming video of the flower - called the Stink Cam.
I humbly announce that tickets to see me today are sold out (and tickets are limited for tomorrow, 7/15)! I’ll be blooming for just a few more hours and then I plan to deflate in a final glorious swansong. It will be DRAMA! Watch me live starting NOW! https://t.co/sXA3EiSDzW— longwoodgardens (@longwoodgardens) July 14, 2020
It is native to rain forests in Indonesia.
The last time one bloomed at Longwood was in 1961.
What do you think? Pantone rubine red? I’m so excited to show off my true colors today. Here’s a fly's-eye-view inside my spathe. Pretty amazing, right? Don’t worry I won’t let all this adoration go to my spadix! https://t.co/gmNJZaKIIe #SproutStinks pic.twitter.com/EqqpZgtKhj— longwoodgardens (@longwoodgardens) July 14, 2020
