Titan arum ‘Wee Stinky’ preparing to flower

For updates on ‘Wee Stinky’ visit the Liberty Hyde Bailey Conservatory news feed.

One of the Liberty Hyde Bailey Conservatory’s two flowering-sized Titan arums is preparing to flower, likely before the end of the year.

‘Wee Stinky’ — the first of Cornell’s Titan arums to flower in 2012 — has broken dormancy. Cornell University Agriculture Experiment Station greenhouse growers expertly moved the pot holding the plant into the bench area at the north end of the Student House where it will flower alongside its sibling ‘Carolus,’ currently in its vegetative stage. (View video of the move below.)

When will ‘Wee Stinky’ open and emit its pungent aroma? It’s hard to say at this point. At just over 6 inches tall, it has a long way to go. The last time ‘Wee Stinky’ flowered in October 2016 its spadix stood 87 inches tall. And we’re unsure how the short days and low light levels will affect the progress of this tropical plant. Our current estimate is sometime in early to mid-December.  As we chart its growth, we’ll get a better idea.

The Conservatory is open weekdays from 10 a.m. to 3 p.m. Stop by to view the Titan arums and the 600 other fascinating plants that make up this living collection.

Cornell Chronicle: Titan arum blooms outside for first time

Both the Cornell Chronicle and CALS News reported this week on Carolus’s historic bloom:

Summer breezes wafting through Cornell’s Minns Garden carried the aromas of fresh grass, notes of floral and, for a few days in August, something akin to rotting meat.

Yet the chance to experience that repugnant odor drew thousands of visitors to the garden near the Plant Science Building. The reason: Carolus, one of the College of Agriculture and Life Sciences’ Titan arums (Amorphophallus titanum), as the giant, smelly tropical plant also known as a corpse flower bloomed outdoors for the first time ever in a region outside of the tropics.

Carolus started its dramatic show Aug. 7, unleashing its mighty rotten-meat stench that, in the sweltering forests of Sumatra, Indonesia, attracts flies, carrion beetles and other pollinators looking for a snack and a place to lay eggs.

Coaxing the plant to bloom outside in the cool of an Ithaca summer takes a lot of nerve and a little luck, said Paul Cooper, the greenhouse grower for the Cornell University Agricultural Experiment Station (CUAES), who cares for Cornell’s two flowering-sized Titan arums.

Thanks to all who stopped by this week to visit Carolus blooming in Minns Garden (map) .

Carolus continues to wane, but will remain outside at least through the weekend if you’d like to take one last look. Soon, Conservatory staff will move the pot inside where the underground corm will remain dormant for a few months before putting out a single huge leaf to begin recharging the corm for next flowering.

Many visitors this week who had visited during previous Titan arum flowerings remarked how different the plant looked outside in a more natural setting. Another big difference: There’s no wind in the Conservatory. Outside, Carolus’s spathe was free to dance in the breeze.

Carolus: Spadix collapsing

Overnight, the tip of Carolus’s spadix tipped over as it continues to dry down. (That’s entirely normal and expected.) There’s still a bit of the arum’s trademark aroma lingering. Stop by Minns Garden (map) for a look.

Carolus: No longer (as) stinky

After putting on a stinky show for visitors to Minns Garden (map) on Tuesday, Carolus has lost most of it’s stink.

The Titan arum reached peak bloom outside early Tuesday morning. The spathe — dancing in the breeze — dried down steadily as the day progressed and is nearly totally desiccated this morning.

But the spadix is still standing and will likely stay upright for at least a few days. It’s hard to know for sure because this is the first time we’ve ever done this outside.

If you stop by for a look, you can also visit Carolus’s sibling Wee Stinky in full leaf touring into the rafters of the nearby Liberty Hyde Bailey Conservatory.  Conservatory hours at 10 a.m. to 3 p.m. most weekdays.
