Dear all,

The plant with the largest inflorescence in the world, Titan Arum (Amorphophallus titanum), is currently in flowering in our medicinal plant garden at the University of Mississippi. The flower-bud is now 3-days old and has grown to over 3 ft tall; at maturity it may reach 7-10 ft high. It may gradually bloom during the next 2-3 days. In full bloom, it emanates a characteristic, strong, unpleasant (rotting meat!) odor in order to attract the pollinator flies. So, it is also known as 'Corpse Flower'.

This is a rare and threatened plant species, native to Indonesia. The plant takes more than 5 years to start flowering and it blooms infrequently (once in 3-5 years). It even more rarely blooms under cultivation. For more details visit http://en.wikipedia.org/wiki/Amorphophallus_titanum

I will post more pictures when the inflorescence opens fully.
 
Regards 

Vijayasankar

Whenever a Titan Lily blooms it makes a news.
And a smell of rotten flesh probably to attract pollinator insects.
You are lucky to see it in front of you.
And thanks for showing this majestic plant in bloom.

Thank you all for your comments and appreciations.
The flower (inflorescence) of Titan Arum looks very attractive, grand and majestic in full bloom!

Wow, thanks Vijay for sharing this wonderful plant. I wonder why this plant need to produce such a big flower putting so much resources. Any idea about its pollinator?

Thanks Giby.
Titan Arum flowers are pollinated by carrion beetles and flies. This way the flowers tap an unusual source of pollinators. Like some other Amorphophallus species, A. titanum also produces heat and the typical (rotting meat) odor simulating freshly killed animal body in order to attract this special group of pollinators.

The plant lives in evergreen forest; it blooms once in 3-5 years and the flowers live just for a day. So it has to be successful in pollination and seed-setting. The flowers (infl.) are large and prominent; and the spadix acts like a torch, producing heat (higher than the surrounding air) so that the odor spreads up above the tree canopy and to greater distances.

Its really amazing!

Thanks Vijayasankar ji
I had photographed this plant from UCBG mostly in fruiting stage in 2008. It flowered again in last week of July 2016, but missed it although I was California, read it only later on. For last one year there were a number of messages on WhatsApp claiming that this plant flowers only once in 40 years. I was tired of convincing people that it is not so.

There was also a rumor that Shivling appeared in the pot. 😇

Thanks Gurcharan ji! Yes, I have seen the beautiful pictures posted by you. Fruit setting is in fact rare in this species as the flowers are not self pollinated. Hence the pollination in garden-grown plants are usually done artificially with stored pollen.
Haha, false news spread faster...!
This species generally blooms during summer at least in the USA. Hope you will be able to see flowering this year. The flower is stunningly beautiful when bloom, and of course, uniquely stinky. But every botanist should experience this giant beauty. We also expect an another bloom this summer.
