Archives For Spike

“Titan Tim” Pollak here, with some thoughts about Spike the corpse flower as he goes into dormancy. I never thought I’d call myself “Titan Tim,” but Spike has forever changed my life—as he did life here at the Chicago Botanic Garden—during the four weeks he was on display in our Semitropical Greenhouse.

Spike brought the nation’s—and even the world’s—attention to the Garden, as we waited for our first-ever flowering titan to open up in all its stinky and colorful glory. The event—and I am proud to call this an event—brought more than 76,000 visitors to see Spike (8,200 people alone on Sunday, August 30, when we manually opened up the flower), making it by far the largest event in the Chicago Botanic Garden’s history.) In addition, there were 948 television and radio stories broadcast and 126 online reports, reaching an unbelievable 173,884,617 estimated people!

I myself did 42 interviews regarding Spike, including television, radio, print, and internet. And I wrote seven blogs along the way, telling the story, history, origins, care, and details about the smell of Amorphophallus titanum, the world’s largest unbranched inflorescence.

During all of the “Spike-mania,” I was often asked if I was getting any sleep. My answer was “Not so much!” Spike became a member of my family, a sort of adopted son that I referred to as “him,” “he,” “mine,” and “ours” in conversation. During those weeks, Spike became my life, 24/7, day and night…and I became “Titan Tim,” for sure.

The power of one plant…Wow!

“When is he going to bloom?” That was the number one question on everyone’s mind, both at the Garden and from visitors. As you know by now, Spike didn’t have the energy to bloom by himself, as we thought he would. (Read the story about it here.)

Finally, we decided to manually open the spathe to check on the viability of the male and female individual flowers inside. If healthy enough, we could attempt to pollinate the female flowers with donor pollen from recent titans at the Denver Botanic Gardens and California’s Huntington Library, Art Collections, and Botanical Gardens. We also wanted to collect the pollen produced by Spike’s male flowers, to preserve some here for the future, to donate to other institutions, and to contribute to global genetic diversity.

We knew we would be giving our visitors a very rare opportunity to see the internal flower structures up close—to observe, touch, feel, and even smell a procedure that has rarely ever been done. What a teaching moment it became! (Spike taught the world about pollination.) At that point, horticulture and science met in the transparency of the public eye. Our horticultural staff had nurtured and cared for Spike for 12 years. Our scientists had long been working to bring attention to the endangered and threatened plant species of the world. And the public was curious and enthusiastic about learning the facts about a “huge, rotten, and rare” phenomenon.

That morning, I experienced the power of one plant—an experience that will stay with me for the rest of my life. Despite the disappointment, Spike was a success: he was a rock star and a hero to the botanical world.

To all of Spike’s Garden friends

To still have people coming by and asking questions well into the week after Spike's spathe was removed was pretty remarkable.

To still have people coming by and asking questions well into the week after Spike’s spathe was removed was pretty remarkable.

The other amazing experience for me was with Spike’s visitors, fans, and “groupies.” He had such a large following, and I often saw some of the same people visit day after day! I heard and received so many positive comments from visitors. People said that Spike was part of daily dinner conversations—that they would converse about when he was going to bloom, how tall he was going to get, and so on. Spike had become a household name! Many of you were devoted watchers of the streaming live cam on our website and on YouTube, and many wrote to say that you saw me every morning checking on him, measuring him, touching him, and smelling him. It was wonderful and humbling, and it made me feel like a proud papa to Spike!

I want to share with you just a few of the many wonderful comments I received via e-mail and in response to my blogs:

From Don H.: “How very cool to experience something so astounding after years of care. I can’t wait to experience it!!”

From Richard F.: “The live cam provides a wonderful tool to watch the flowering progress 24/7. Thank you for this initiative.”

From Chicago Catt: “It’s fascinating. Thank you for bringing this to Chicago!”

From Marjorie R.: “The anticipation is killing me! I’m going to be one of those people showing up at 2 a.m. I have been watching the webcam online every day at 2 a.m. to check on him!”

From Nicole R.: “Tim, I need to know: Are you sleeping with Spike these days? …Please assure us you are there, encouraging it, protecting it, and maybe even hugging it from time to time.”

From Heeyoung K.: “Dear Tim, First of all, I was amazed how you and your team turned Spike’s sad ‘failure’ to bloom into (an) even more wonderful learning experience with heartwarming support from so many people. I would say that was (the most) monumental event that has ever happened to a ‘mere’ plant :).”

From Lynn Q.: “Even though Spike didn’t bloom as we all hoped…the whole ‘Spike experience’ orchestrated by the Garden and all of the specialists working with Spike was just fantastic. I loved learning about these plants through frequent visits and reading the information on the website. Best of all was the opportunity to monitor growth through the live cam: we viewed Spike from time to time at home. Thus, I write to thank you and encourage you on the next efforts with these amazing plants!”

Thanks to all who wrote and reached out to me during Spike’s time on display. From myself and all of us at the Garden, we simply can’t thank you enough.

The silver lining in the story of Spike is that we have more titans to come. Seven other Amorphophallus titanum plants are in various stages of leaf, dormancy, and growth in our production area, and sooner or later another will be on display for you all to come and experience. Keep checking our website for updates on these rare and unusual plants.

The corpse flower will return in the future…and so will “Titan Tim.”

About That Smell…

Tim Pollak —  August 15, 2015 — 10 Comments

The night Spike blooms will thrill us all in the semi-tropical greenhouse, with its breathtaking flower…accompanied by a titanically rotten smell. 

“Your heart is full of unwashed socks, your soul is full of gunk, Mr. Grinch. The three words that best describe you are as follows— and I quote: stink, stank, stunk!”
—Dr. Seuss

“Titan Tim” Pollak here once again, with an update on Spike, our still-growing titan arum. Spike continues to get bigger, not only in height, but also in girth! What we’re really curious about, however, is the aroma.

The stench is one of the cool reasons to stay up late and come to the Garden that night—we’ll be open from 9 p.m. to 2 a.m.

Here’s what to expect in terms of scent:

What an "arum-atic" combination of scents!

What an “arum-atic” combination of scents!

  • As the spathe gradually unfurls, the spadix releases powerful odors meant to attract pollinators. The potency of the aroma gradually increases from late evening until the middle of the night and then tapers off as morning arrives.
  • Analyses of chemicals released by the spadix show the “stench” includes dimethyl trisulfide (like limburger cheese), dimethyl disulfide, trimethylamine (rotting fish), isovaleric acid (sweaty socks), benzyl alcohol (sweet floral scent), phenol (like Chloraseptic), and indole (like mothballs).
  • The titan arum’s odor has been described in many other terms as well: rotting flesh, rancid meat, rotting animal carcass, old dirty socks, and even the smell of death itself, which accounts for the plant’s common name, the corpse flower.
  • In its natural habitat on the island of Sumatra in Indonesia, the “fragrance” is used to attract the carrion-eating beetles, dung beetles, and flesh flies that pollinate the titan arum. The inflorescence’s deep red color and texture contribute to the illusion that the spathe is a piece of meat.
  • During bloom, the tip of the spadix is approximately human body temperature, which helps the fragrance volatilize (turn to vapor) and travel long distances; the heat may also advertise that there’s a fresh carcass for insects to check out.

A different view of ewwww!

Carrion beetles, dung flies, and flesh flies aren’t responding to the call of the titan arum’s scent because they want to be pollinators—they’re responding because they want a good environment in which to lay their eggs. 

In the wild, mama beetles and flies lay eggs on dead animals or animal feces knowing that the larvae that hatch will have an immediately-available, rich source of food.

In its natural rainforest habitat, the titan arum has adapted to that fact. Over evolutionary time, it has developed the right scent to attract those insects—and, like many scented flowers, to deceive them with scent into acting as the unwitting spreaders of their pollen. 

Keep checking back for more on Spike’s progress!
