UPDATE:

Little Stinker started to unfurl at 7:00  this evening (7/28).  It should be fully open Thursday, July 29th. 
This is a unique opportunity to witness the private life of a plant on a massive and pungent scale.
Director Paul Licht will pollinate Little Stinker tomorrow morning and this may shorten the bloom duration, so plan to come early.
The Garden will stay open until 7 PM on Thursday July 29th.

New titan arum bud discovered on the afternoon of 7/16/10.
This plant is only 20" high but is already at least several days past the stages we usually start predictions.
Opening in small plants seems faster but the best guest now is 8-11 days (compare it to Maladora on June 19).

Titan Arum Naming Contest

And the Winner Is....

The new titan bloom is 'MALADORA'. The winning name was suggested by Mayumi Webber. We received 129 great nominations and selected MALADORA for the wonderful play on the malodiferous; it's an adorable malodor. Thank you to everyone for the clever and thoughtful suggestions; it was not an easy decision.

The legendary Sir David Attenborough first used the name titan arum to refer to this magnificent tropical plant in the BBC series The Private Lives of Plants because he felt viewers might be offended by the plant's Latin name, Amorphophallus titanum. Titan arum might have suited Attenborough's viewers, but the plant still seduces people with one of the world's largest and rarest flowering structures and and a reproduction method that beguiles insects with the illusion of decay in appearance, odor and even temperature; hence the name 'Corpse Flower'.

Generally fewer that five titans bloom each year in the US. Here's your chance to see a bloom first hand at the
UC Botanical Garden. Our plant is starting to open. The flower is only fully open for a day or two, and the best way to follow the flower's progress is on our website, Facebook and Twitter posts.

The largest flowering structure in the plant world belongs to Amorphophallus titanum, affectionately known as the “Titan Arum” or “Corpse Flower”. This structure is actually not a single flower but an inflorescence (a stalk of many flowers). The flowers are a mixture of tiny male and female flowers held out of sight at the base of the central phallus-like structure (spadix) surrounded by a pleated skirt-like

6/29/2010 --- Started to open at 2-2:30pm. Opened quickly until 6:30 to 25" wide. No strong odor but definite pulses.
6/30/2010 ---

(7am) Fully open at 34" spread. Smell persisted in pulses all day. Pollen extrusion just beginning at 6pm

7/1/2010   Closed to about 24". Lots of pollen in bottom

covering (spathe) that is bright green on the outside and deep maroon inside when opened. The female flowers mature before the male (pollen producing) flowers to avoid self-pollination. 

Ever since this plant was first discovered in Sumatra, Indonesia in 1878 by Italian botanist Odoardo Boccari, it has excited world-wide attention due to its massive size, fascinating appearance and habit of producing a foul odor resembling rotten flesh (to attract insects that pollinate it).  To assist in the process, the ‘flower-spadix’ actually heats up (to human body temperature).

This plant and its relatives are members of a genus often referred to as Voodoo lilies in the arum family (Araceae). Common relatives include the philodendron, calla lily and cobra lily (the Jack-in-the-pulpit of eastern US).  These have an underground tuber.

The plant typically requires at least 7 years of age before it blooms but may go much longer.  Trudy arose from a seed collected in Sumatra in 1995; it first bloomed here in July, 2005 (at age 12 years).  The tuber (swollen underground stem) must reach at least about 30 pounds before blooming. Trudy’s tuber now weighs 54 lbs and fills the pot, requiring constant watering and food. After blooming, Trudy ‘rested’ for 4 years, producing a large leaf and replenishing its tuberous stores.

In the normal life cycle, the plant produces a single enormous branched leaf that looks like a small tree reaching 10-15 ft (on display in the Tropical House). The leaf will go completely dormant after about 16 months and the tuber then ‘rests’ for awhile. When it next sprouts, it will produce either another single leaf or the enormous bloom.

The flower bud may take months to form but then only remains open for a day or two before collapsing to restart the cycle. The characteristic ‘corpse’ odor is only produced about a day before the collapse. Trudy’s first flower in 2005 reached 5.5 ft, but it looks like this flower will be taller.

If pollinated, the stalk grows into a large club-like head of orange-red seeds.
