Learn about Amorphophallus titanum: The Corpse Flower

Amorphophallus titanum aka the Titan Arum or the "Corpse Flower" is one of the largest, rarest, and smelliest flowers in the world. It can grow to a height of 7-10 feet and when it flowers it can have a diameter of 5-6 ft PLUS (and this is how it gets its name) when blooming it smells of rotting flesh!

This site provides links to websites providing information about the Amorphophallus titanum. It includes images of the Corpse Flower and videos of its growth and statistics about the dimensions of different examples

ALL ABOUT Amorphophallus titanum a.k.a. the Titan Arum a.k.a "Corpse Flower"

Features of the Titan Arum:

* Amorphophallus titanum (aka Titan Arum) is VERY RARE in its native home of Sumatra - and even rarer outside Sumatra. It's classified as Vulnerable (V) on the 1997 IUCN Red List of Threatened Plants.

* The titan arum can be found in the rainforests of western Sumatra, on steep hillsides that are 120 to 365 metres above sea level.

* The Titan Arum VERY RARELY FLOWERS - only once in a 1,000 days once it's reached an age where it can flower

* Titan Arum has flowered 29 times in the USA since records began - but there are fewer than 29 plants.

* This is a plant which grows taller than a man - it's common for them to be over 6 feet tall

* It produces THE BIGGEST FLOWER IN THE WORLD. A single inflorescence can be around about four feet across

* Technically it's lots of very small flowers - male and female - surrounded by a coloured leaf ( a special form of bract - called a spathe) which is commonly mistaken for the flower

* Usually it has a single spathe/flower colored deep burgundy - but it can produce more than one inflorescence (see Bonn video below)

* The flower typically only lasts about three days

* The record for the tallest inflorescence has been set by a Titan Arum located in Bonn, Germany. In May 2010 it produced a bloom nearly nine feet (2.74 meters) tall above the soil. Its total height, including the tuber under the soil, was 11 feet in (3.40 meters)

* Most well known for producing a VERY STRONG STINK of "putrefying roadkill" - hence its nickname of "the corpse flower"

* it's actually the big spike in the middle which produces the smell

* It only smells when the female flowers are receptive to pollen

* The flower is at its fullest (and foulest) during the first 12 hours of its bloom when it is at its peak fertility

* It's thought the stink is to make sure that pollinators find it in its natural habitat of the Rain Forest

* In the wild it's pollinated by carrion-seeking insects

* In 2009, David Attenborough gave it the short name of "Titan Arum" as its proper latin name is very long and sounds a bit rude!

* In 1878, Italian botanist and explorer Dr. Odoardo Beccari discovered it in the rainforest of central Sumatra

* Titan Arums are typically only now found in tropical rainforest in Sumatra or in large botanical gardens

Each time it blooms it typically attracts thousands of people who will stand in line to view this amazing plant

Botany of the Titan Arum - the Corpse flower - which bit is which?

TOP THREE THINGS TO KNOW:

1. It's not one flower - technically it's a group of male and female flowers (an INFLORESCENCE), but they always grown together so it can be considered as one flower

2. The big spike in the middle is called the SPADIX- and this is what supports the Inflorescence and creates the smell to get insects to come and pollinate it

3. What people think of as the flower is actually a very special sort of leaf called a SPATHE. This is a bract leaf and it's normally a deep purple colour. It unfurls very slowly from the spadix. Before it starts unfurling it tends to sag and look a bit "pregnant" and its girth widens prior to flowering

  • Inflorescence - Wikipedia, the free encyclopedia
    An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Strictly, it is the part of the shoot of seed plants where flowers are formed and which is accordingly mo
  • Spadix - Wikipedia, the free encyclopedia
    In botany, a spadix (pl. spadices) is a type of spike: an inflorescence with small flowers crowded on a thickened, fleshy axis.
  • Spathe (Bract) - Wikipedia, the free encyclopedia
    A spathe is a large bract that forms a sheath to enclose the flower cluster of certain plants such as palms, arums, and dayflowers. In many arums, the spathe is petal-like, attracting pollinators to the flowers arranged on a type of spike

Titan Arum Taxonomy

* Class: Equisetopsida

* Subclass: Magnoliidae

* Superorder: Lilianae

* Order: Alismatales

Titan Arum Flowerings in Europe

Titan Arum flowers at Kew Gardens - a timelapse video from Kew Gardens on YouTube

One of the most spectacular plants to be found in the wet tropics zone of Kew Gardens' Princess of Wales Conservatory is the titan arum. With its huge flowering structure (inflorescence) rising over 2.5m above the ground and its single immense leaf, it certainly is a giant among plants, as its name suggests. Coupled with its characteristic foul stench, and the rarity of flowerings, this plant has always hit the headlines.

This plant is also renowned for flowering on a regular basis. The Kew Gardens Facebook site usually announces when it has flowered

The Corpse Flower in Bonn - Largest Bloom - Botanische Garten der Friedrich-Wilhelms-Universitat Bonn

The plant has an underground tuber, which can weigh up to 75 kg. This tuber produces a single, multipinnate leaf, which can grow up to 6 m tall and nearly as wide. This leaf lives for 9 to 24 months and, during its lifespan, it delivers the energy for a new, larger tuber.

At irregular intervals of several years, instead of a leaf, the tuber produces a colossal inflorescence, which can grow more than 3 m high and 1.50 m wide

Flowering titan arums in Bonn are almost traditional by now - the event in May 2006 marks the ninth and tenth time, after 1937, 1940, 1987, 1996 (two plants), 1998, 2000 and 2003.

Ouch, did I say The Eden Project? A senior moment, it was of course kew Gardens.

John Dyhouse from UK on August 26, 2012:

Such a lot of information, I am going back to look at the videos. I remember the flowering at Eden (the project) which was widely reported on TV and in the newspapers. I made an ATC in watercolour - such a small sketch for such a huge flower; it is still on Flickr. Thanks for all the background info, a massive task for you.

Katherine T (author) from London on May 31, 2011:

@anonymous: Well you're the same part of the world in tropical terms so I guess it's entirely possible that you've got one. Most of the ones seen in public today are being grown outside Sumatra in botanical gardens

anonymous on May 30, 2011:

this may sound pretty odd, but i think one of these stinky things' actually blooming a foot away from my fence. the neighbors are freaking out because of its foulness and everyone's talking about weird case scenarios since no one claims to have planted it there, let alone having wanted to plant it there. I believe these only grow naturally in Sumatra, now that's kind of far from where I live, Cebu, PHilippines. your thoughts?

Steve Dizmon from Nashville, TN on March 11, 2011:

I had heard of these, now I know a lot about them. Interesting lens on an unusual subject.

Katherine T (author) from London on February 11, 2011:

@ShamanicShift: Thanks!

anonymous on January 13, 2011:

I actually had one growing in my front yard. Didn't know what it was -- didn't even see it at first, just smelled the rank smell. Figured it was a dead decomposing rat -- went looking for it in the yard and found a small orangish cone that was evidentally a very young corpse flower. Still had no idea what it was -- just knew it smelled horrible and wouldn't go away. Figured it was an undesirable weed and destroyed it.

ShamanicShift on January 11, 2011:

I saw and whiffed in the botanical gardens here in Milwaukee -- SquidAngel BLESSED!

spunkyduckling on November 29, 2010:

That really must be a spectacular flower. It's size sound scary to me but very interesting too.Thanks for sharing about the corpse flower. Oh well..I am going to sleep now. I have been trying to get some lenses together for the Christmas rush and I am all choked lol.

Diana Grant from United Kingdom on November 29, 2010:

This plant (and your lens) is fascinating - although I am keen on gardening I hadn't heard of the corpse flower before.

I have black lilies in my garden, which must be a relation to the larger plant. They smell bad and only last a very few days, so are really rather useless plants for a small garden, but they have beautiful sculptural leaves and are so unusual that, not only do I not get rid of them, but I also encourage others to have cuttings, and there must be 5 or 6 people who have benefitted from my little rarities. Lensrolling to some of my gardening lenses.

Katherine Tyrrell from London on July 23, 2010:

@myraggededge: Many Thanks! I've not come across one which ponged - just the ones that assault you with their indelible pollen! :)

myraggededge on July 23, 2010:

Fascinating page on a flower that I just would not want in my garden or any garden near by! Mt granny had a small lily that used to pong too and however much she tried to get rid of it, it kept coming back - I wonder what that was?

Blessed :-)
