Penelope the corpse flower is in bloom at Milwaukee’s Mitchell Park Domes.

Penelope, which last bloomed in 2024, will be open and stinking for the next 24-48 hours. This rare and very large flower only booms every couple of years; when it does, it emits a powerful – and disgusting – odor.

“Typically they only bloom once every six to eight years, ” said Amanda Garchow, horticulturist at the Domes. “Penelope’s a little different in our case; this is her second bloom in two years, so it’s extra exciting for us because it’s a rare event that’s she’s blooming so soon.”

The ephemeral nature of this plant and its experience has gathered somewhat of a cult following, according to Bryan Connolly, botanist and associate professor of biology at Eastern Connecticut State University, who once had someone visit his greenhouse with a corpse flower tattoo on his leg.

Below, with some help from Connolly and Garchow, we answer questions about this fascinating plant.

What exactly is a corpse flower?

The corpse flower, also known as a Amorphophallus titanum to scientists and “titan arum” to fans of David Attenborough’s “The Private Life of Plants,” is a flowering plant native to rainforests on the Indonesian island of Sumatra. It is known for its putrid smell, often compared to the scent of rotting flesh, and for only blooming for 24-48 hours every couple years.

Why does it take so long to bloom?

It needs to accumulate enough nutrients. The corpse plant starts as a seed or, if it’s already bloomed, an underground tuber-like corm (think potato). Both produce a really large leaf, which can be up to 15 feet tall.

“There’s no stem when it’s not flowering, and so it has a petiole, which is part of the leaf that looks kind of like a stem, but it’s not a stem,” Connolly explained. “They can get very large, like bigger than your thigh around.”

The leaf generates sugar – food for the plant – and stores it in the underground corm.

After a year, the leaf dies, and the tuber rests for four months. Then it produces a new leaf and repeats the cycle until the tuber becomes large enough. This takes about seven to 10 years for a new seed and three to four years for a corm that’s bloomed before.

The corm of a corpse flower is the largest of any flowering plant. According to Connolly, the biggest one has been up to 200 pounds, but they’re typically more like 60 pounds.

Why the rotting meat smell?

To attract pollinators. After years of tuber growing, the tuber eventually produces a spike, formally known as a spadix, of flowers wrapped in a specialized leaf called a spathe. Female and male flowers grow in a ring at the bottom of the spadix. This stage is called an inflorescence, which is a group of flowers.

The corpse flower is the world’s largest unbranched inflorescence or group of flowers.

Eventually, as the spathe opens, the spadix heats up to about 99 degrees F and the flowers begin to emit pulses of powerful odor to attract insects, like carrion beetles or fruit flies, that typically eat or lay their eggs on rotten meat. These insects pollinate the flowers at the base of the plant.

Are there benefits to being pollinated by insects like fruit flies and carrion beetles instead of more common pollinators like bees?

Not really.

According Connolly, it may be related to the plant’s native environment. Corpse plants can be miles apart in a rainforest, and since they bloom infrequently they can only be pollinated and reproduce every few years. Because of that, it could be advantageous to seek pollinators that are willing to travel long distances between plants.

What makes it smell so bad?

Chemists have isolated identified over 40 compounds that make up the odor released by the plant. Some of the chemicals include two that smell like garlic (dimethyl trisulfide and disulfide), one that smells like sulfur (methanethiol), one that smells like citrus (limonene), one that smells like feces (idole), and one that smells like urine (phenylalanin).

Why should I care?

There is inherent intrigue to a smelly plant named Penelope. But also, corpse flowers are an endangered species due to loss of habitat, climate change and encroachment from invasive species. Garchow said that it’s estimated there are only 800 left in the wild.

Additionally, these plants are difficult to conserve via seed preservation because their seeds aren’t viable after drying.

Therefore, they must be conserved in living collections in gardens, research labs or greenhouses and conservatories like the Domes.

Since they can’t self-pollinate, despite having both male and female flowers, they must be pollinated by another plant. Different research labs and greenhouses often rely on sending stored pollen to each other to keep these plant lines going.

“I’m really thankful that we have this giant, smelly, weird plant that, you know, kind of brings botany to the public,” said Connolly with a smile. “And just the conservation of plants and of the species in general.”

The Domes will have extended hours on Saturday and Sunday to accommodate visitors who want to see the corpse flower in bloom, though the smell will mostly fade by Sunday. Stop by to see Penelope, support important conservation work and acquire a unique, albeit smelly, experience.

The Dome, 524 S. Layton Blvd., will host extending hours for this event, from 8 a.m. to 4 p.m. both days. Admission is $10 for adults ($9 for residents), $6.50 for ages 3-12 and free for children younger than 2. Due to road construction and the closure of the 27th Street bridge, the Milwaukee Domes Alliance suggests using GPS to plot a route. Directions and more information, including specific discounts, are available at www.MilwaukeeDomes.org.

MILWAUKEE – Garrett Mitchell and William Contreras homered, Jacob Misiorowski delivered another winning performance, and the Milwaukee Brewers beat the rival Cubs 6-2 at American Family Field on Friday night.

Jacob Misiorowski

By the numbers:

Misiorowski (9-3) struck out eight over six innings and 105.5 mph, tied for the third-fastest since pitch tracking began in 2008. He allowed one earned run – a Seiya Suzuki home run in the fifth – on two hits but walked four. His earned run average for the season now sits at 1.45.

Home runs at AmFam

By the numbers:

Milwaukee trailed 1-0 when Misiorowski threw his final pitch of the night, but Mitchell belted a two-run home run in the bottom of the sixth to put Miz in position for the win. David Hamilton made it 3-1 with a triple that scored Cooper Pratt later in the sixth.

Contreras added insurance with a two-run home run of his own in the seventh. Suzuki drove in Pete Crow-Armstrong with a sacrifice fly in the eighth to close the gap for Chicago, but Christian Yelich doubled home Pratt in the bottom half.

Abner Uribe pitched a scoreless seventh for his eleventh hold of the season, Aaron Ashby gave up the sac fly to Suzuki in the eighth and Trevor Megill walked one but worked a scoreless ninth.

Former Milwaukee pitcher Colin Rea pitched five innings in the start for Chicago, but Ethan Roberts was credited with both the loss and a blown save. 

Brewers manager Pat Murphy, who had surgery Thursday for a ruptured disk in his back, guided his club from a safe spot near the dugout.

Saturday’s game

What’s next:

LHP David Peterson (3-6, 6.09 ERA) makes his Cubs debut after being acquired Thursday from the New York Mets for minor league third baseman Cole Mathis. LHP Kyle Harrison (8-1, 2.50) starts for the Brewers.

There are few things that the Milwaukee Brewers haven’t done right so far in 2026.

Milwaukee has navigated difficult injuries all season and yet it is 49-29 and has the second-best record in baseball behind the Los Angeles Dodgers (52-29) heading into an important series against the Chicago Cubs. How many teams out there could accomplish this feat when guys like Andrew Vaughn Christian Yelich, Quinn Priester, Jackson Chourio, and Brandon Woodruff all missed significant time at various points in the season? These are legit, star-level pieces and the Brewers navigated the losses admirably.

Right now, all of them are healthy, except Priester. The young starter will miss the entire season. Now, Milwaukee is firing on all cylinders and yet it could be even better. Soon enough, Logan Henderson will be back. Also, the offense would arguably be even better if Vaughn was given more opportunities. Since May 4, Vaughn is only eighth on the team in plate appearances, per Curt Hogg of the Milwaukee Journal Sentinel.

Despite this, Vaughn has done nothing but tear the cover off the ball. In 39 games, he has slashed .355/.444/.542 with a .987 OPS, two homers, 12 doubles, and 23 RBIs. That’s the type of production you need in the lineup every night, regardless.

The Brewers Need To Give Andrew Vaughn More Time

Brewers manager Pat Murphy acknowledged that Vaughn has had a weakness with some righties, as transcribed by Hogg.

“Heavy east-west sometimes is more troublesome for him,” Murphy said. “But for him this year you can look at it and go, ‘Yeah, against the two-seamer he’s been [worse]. But what about the times against the two-samer that he took it and got something else? You don’t get credit for being good against the two-seamer when you take it. You only get dinged when you swing at it.”

Still, this is a guy batting .355 since May 4. He’s obviously not perfect, but Milwaukee’s offense is better with him in it. Even if the club has to get creative. Jake Bauers has made his mark this season and needs playing time as well and both play first base, among others. Throughout Vaughn’s career, he has seen time at third base, second base, left field and right field, along with first base. Throughout the season to this point, there’s been chatter about how the Brewers haven’t had enough offense on the left side of the infield.

They recently promoted Cooper Pratt to play shortstop, so third base has been handled by David Hamilton and Joey Ortiz. Maybe a good idea could be trying to shift Vaughn to third base for the time being because they could then get his bat and Bauers’ bat in the lineup consistently. In that scenario, the Brewers could also consistently roll with an outfield of Chourio in left field, Garrett Mitchell in center field, and Sal Frelick in right field.

At the end of the day, the Brewers need Vaughn’s bat in the lineup every day. If you can bat .355 over a 39-game stretch, you deserve significant playing time.
