66.2003. Royal Botanical Garden/Kew/England. 6/10/2003. �2002/3 - the specimens which flowered in 2002 and 2003 were grown both from seed donated to Kew in 1995 and from tiny micro propagated plants received from the botanic garden in Bonn in 1995. To build up the storage corms, they were potted on into 750 liters (198 Gal.) containers in 1999 although they were in full leaf at the time. When the leaves died down, the largest corm was placed in a 1,000 liters (264 Gal.) pot and the two smaller ones were put into new compost in 750 liter pots. For the next 14 months, they were grown behind the scenes at Kew in their Tropical Nursery. The plants were fed regularly with a high potash liquid fertilizer. In January 2002, while the plants were dormant, they were potted up again. The largest of the three corms, one of those grown from seed, weighed an astonishing 75 kg (165 pounds). As the new bud started to emerge the plant was transferred to the Princess of Wales Conservatory. During the day, the temperature is at least 24�C and at night it drops no lower than 19�C. The humidity is maintained at 70-80% � mimicking the conditions prevailing in the plant�s original rainforest� habitat.

69.2003. University of Washington/Seattle/USA. 8/06/2003. Spadix grew 2.13 m. (7 feet) high. Corm weight was 51.25 Kg. (113 pounds). Accession # is 4260-1.


70.2004. Cibodas Botanic Garden/Bogor/Indonesia. 3/11-14/2004. Spadix grew to 2.89 m. (9.5 feet) high.


71.2004. University of Connecticut/Storrs/USA. 7/6/2004. Spadix grew to 1.5 m. (4 feet, 11 inches) high. �Corm repotted; Corm weighed 89.5 pounds and was 0.54 m. (21 inches) in diameter. Corm in good shape and repotted into herbaceous mix in new 45 gallon container. Since they were doubtful whether pollination was successful, they opted to voucher the inflorescence shortly after it toppled.  It did stink really bad, but never fully reflexed as most do. We suspect that one (or both) of two things caused this bloom to act abnormally. First, due to decreased steam during summer months, the tropical house frequently dips into the mid to lower 15.5 C. (60' F) at night, even with thermostats wide open. Secondly, there were 24 hour security lights on just outside the greenhouse due to a construction project - this presumably threw off the plants circadian rhythm and thus the delay and unusual flowering times�.


 72.2004. Stephen F. Austin State University Mast Arboretum, Nacogdoches/Texas/USA. 7/12/2004. Spadix grew to 1.55 m. (5 feet, 1 inch) high.

(26 pounds) in March 2004.  "Big Jack" took four years to bloom. Fresh pollen from the University of Connecticut plant (which was just finishing bloom) was used in a pollination attempt; however, that failed. Pollen from �Big Jack� was shipped to Disney world plant and that pollination attempt failedas well.  Jack collapsed after 91 hours open.  For more information on this blooming event:

"Little Stinker" The smallest of the three corm to flower in 2004. Before full bloom plant was kept in main lobby of Birge Hall (Botany Department). Since the temperature and humidity were low in the lobby, plant moved to the Botany Greenhouse for higher temperature and humidity to give it a boost to open up the spathe. After 48 hours in the greenhouse bloom was given 100 ppm of ethylene gas for 12 hours and next day spathe unfolded.

The spathe did slightly open and emit odor, but the stunting of the inflorescence turned out to be due to rot in the corm. They could not save the corm. There are still 2 large plants remaining in their collection and they've acquired 5 more seedlings for the future. So they looked forward to applying what we've learned from our mistakes to future flowerings.


97.2005. Royal botanical Garden/Kew/England. 9/28/2005. " A third titan arum for 2005 flowered on 28 September, a little later than earlier estimates, perhaps due to the cooler autumn temperatures and shortening day length.
