Justice for the stinky plant languishing at Auckland Zoo

Are we too modest when it comes to celebrating our putrid plant life?

She’s beauty. She’s grace. She smells like a decaying corpse and lurks in the backrooms of Auckland Zoo, wallowing tragically in a bucket. 

In recent weeks an Australian corpse plant named Putricia has captured the noses and imaginations of thousands around the world. She’s had a livestream, at least 15,000 guests lining up before even unfurling, and a piece in Vogue, where she’s been named “The Internet’s Stinkiest It Girl”. And in New York, another corpse plant had people queueing in the cold for hours to catch a whiff.

Meanwhile, one of New Zealand’s own Putricias languishes in obscurity. She has no name. She has no fanfare, no velvet curtain, no cultish devotees. She was kept in the ectotherms team room, says a source, “ominously growing” in a bucket (“we hoped it moved before it was stinky”). She was briefly on display, then relegated to an industrial aquarist pump room. 

Last December, she bloomed her little heart out, exuding her effervescent pong to the world. Harold*, an employee at Auckland Zoo, recalls three people lining up. He was one of them.

She smelled like shart, Harold says, especially in the evenings, when her tip engorges and becomes more pungent. People wanted to sniff her. Many just didn’t know she was there. 

“There were people calling asking just to see the plant – and people getting angry after us taking it off display. People don’t realise they only bloom for three to five days – five is lucky – until the tip starts to sag.” Harold continues talking about her smelly, swollen tip for a while longer. 

New Zealand has had some corpse plants proudly on display. The Auckland Wintergardens amorphophallus attracted “hundreds” of visitors when it bloomed in 2020, described as smelling of “dead rat, but with added sulphurous odours with faeces”. In 2021, I was one of thousands in Dunedin lining up in the Botanic Gardens for a precious whiff. To my knowledge, none of these plants have had names. 

Using a PI and some hired goons, I tracked down the Auckland Zoo corpse plant’s dad. Ben Goodwin, now a lecturer, was an ectotherms keeper at the zoo, and grows amorphophallus (meaning “deformed penis”) species as a hobby. He obtained her from a seed donor on Facebook, though isn’t sure where they got it from – perhaps imported. When she got too big, he left to buy milk and never came back. 

“I don’t really miss the amorphophallus,” he says, ruthlessly. “I owned it, but I kept it at work nearly the entire time it was mine. It was just too big and too demanding of a specialised habitat – real hot, real humid – to grow at home.”

“They did put it on display when it flowered last year, but they didn’t really seem to make much of a big deal about it,” he explains. There were a couple of social media posts, and they had the flower on display for a while, but then it all blew over. “It should have been much bigger news,” Goodwin says. “I’m sure they realise this now and hopefully won’t be caught out next time it flowers.” (This possibly will happen within the next few decades, so hold onto your britches.)

The issue, Goodwin reckons, is that “zoos are too fixed on animals.”

“I don’t think plants are perceived as having the same level of interest to the public, but plants are just as interesting as animals and just as worthy of attention. Auckland Zoo has an incredible collection of plants, but the gardens are treated as a backdrop to the animals rather than something significant in their own right.”

In the 1900s, zoos became more naturalistic, using habitat design to create an immersive space for both animal and visitor. I recall some positive feedback from a guest at Wellington Zoo, who’d not seen many animals but greatly enjoyed her inner-city bushwalk nonetheless. When walking through Auckland Zoo, it’s likewise easy to forget you aren’t really in the South American rainforest, but instead at Western Springs

Flowering amorphophallus are probably the biggest single draw cards for public plant collections, says Goodwin (see: season 14, episode 22 of The Simpsons, ‘Moe Baby Blues‘). “There are well documented examples of extremely high visitation for botanic gardens all over the world … I’ve spent my whole career trying to get people interested in less charismatic animals and plants. I think everyone should enjoy all parts of the natural world, not just the showy stuff. It’s all interconnected.”

I think back to Joel MacManus’s brave condemnation of the bucket fountain, decrying it as a symbol of New Zealand, understated and self deprecating. Why do our Putricias not deserve adoring flocks of fans? Where are her velvet ropes and curtains? 

In reality, zookeeping is mental, and there’s little time to prioritise a plant when over 2800 animals need husbandry. I do not, at all, blame Auckland Zoo, which is a world-leading facility in conservation and animal care (hire me please). I do think that we should give ourselves freedom to be vainglorious, extravagant, and camp. Let’s embrace our weird little freaks. Wherever she is, and whoever she is, I hope our next Putricia gets the stinky fame she deserves. 

Keep going!

What are ‘winged wētā’ and are they taking over?

An Australian wētā lookalike was first noticed in Pukekohe in 1990. Now the stroppy biting insects are common from Auckland up to Cape Reinga.

New enemies have been appearing in my house. They’ve got a big head, long spiky legs, a lumpy abdomen and antennae longer than their body – features that defined them in my head as wētā, a beloved and feared native icon. But when I tried to sweep the bug from my sink into a jar, it got angry. Really angry. This was not one of the gentle giants that Ruud Kleinpaste can’t resist placing on his face. This one was snapping its mouth-pincers and on its back were translucent laced wings.

“They have pretty fierce mandibles,” says John Early, Auckland Museum’s research associate of entomology. They’ve also got “quite a bit of attitude, and are quite stroppy”. He explains that though their looks have earned them the name winged wētā, these bugs are not wētā at all. They’re a species of pterapotrechus – crickets from Australia called raspy crickets, wood crickets or leaf-rolling crickets in their homeland.

Early can vouch that those mandibles are not just for show – in December 2008, when they were just starting to pop up in central Auckland, someone brought one into the museum, alive. Early kept it in a big container with a little pot plant “for a while” in his office. He kindly fed it with mealworm larvae, but one day “it bit me”. Now, that bug is a pinned specimen in Auckland Museum’s entomology collection, along with 20 other pterapotrechus and hundreds of thousands of other bugs.

In New Zealand, pterapotrechus were first discovered in a house in Pukekohe, South Auckland, in 1990. How it got there remains unknown, but Early thinks it was probably an “inadvertent hitchhiker” that slipped through biocontrol. “For years, they were only ever found sporadically, sort of within a couple of kilometers’ radius of Pukekohe Hill,” he says. Then one or two popped up in the Coromandel Peninsula in the late 1990s and after that they started appearing “out Waiuku ways” and around Auckland. Now, they’re “really common” throughout Auckland and all the way up to Cape Reinga. Just a few weeks ago Early found some “just hiding” under the creeper on his fence. “As I trimmed it, out they popped.” 

Early attributes their gradual spread not so much to their wings but rather their sneaky behaviour. During the day, winged wētā hide in little nooks – shoes, drawers and even inside garden hoses. “I suspect they get shifted around as people shift house and move all their goods,” he says. He expects that soon they will be hitching rides south to Waikato and beyond.

Though they’re carnivorous, bitey and easily angered, whether they’re truly evil remains to be seen. For Early the “big questions” are the effects they could have on native species: are they going to be voracious predators and wipe things out? Will they outcompete our native wētās? Will they invade native forest habitats? “It’ll take ages before someone finally gets around to doing a study on it,” he says, because unless there’s already strong evidence bugs are a threat or problem, “there just won’t be any funding”.

He does offer up another set of bugs as a comparison. The whē, our native praying mantis, has “basically disappeared” from large areas. “I don’t think you’ll find it in urban Auckland any more,” he says. Since the 1970s, another mantis has appeared instead – the South African praying mantis. While the whē is always bright green and adults have purple dots on the inside of each foreleg, the South African praying mantis’ colours can range from brown to bright green and have no lovely dots. Also, our native female does not eat her mate, though a few native males have been lost to the appetites of South African females

Non-entomologists have probably not noticed the difference, you have to look closely and know what to look for. A 2011 article in the Forest and Bird magazine says that the South African mantis has “proliferated pretty much unmolested” as a wolf in sheep’s clothing and taken over. Early says that the decline of the whē is possibly tied to other factors too, like the arrival of Asian paper wasps. Still, the South African mantis “certainly is out-competing our native one”.

So should I simply squash my new enemies in a bid to eradicate them instead of risking a bite trying to relocate them outside? Early doesn’t think so. “I don’t think there’s much point, really, because they’re truly here to stay.” I get the feeling unless it’s for scientific purposes, he would advocate no bug being squashed ever. The problem with bugs, he says, is that people “give them a pretty bad rap and just think that they ought to be squished”. Without them, he says we’d be “knee-deep in waste and stuff that didn’t break down.”

Early reckons the next time a winged wētā pays me a visit, I should keep it. Put it in a container, give it a little pot plant, and watch it. “They’re interesting creatures,” he says. It might lay eggs in the soil, or spin a shelter from silk, like his did in 2008. The bite, it seems, has been forgiven.
