The Titan Arum flowered the last time at Bonn in Juli 2000. The flower with the shape of a fountain has had a diameter of 1,5 m and reached almost 2,60 m in height.  It was the third largest flower of the Titan Arum in cultivation ever.  Within 3 days the plant - strongly smelling of decaying fish - attracted some 15.000 visitors to the Botanic Garden of the Poppelsdorf Castle. At this time the tuber had a weight of 36 kg. In 2001 it produced a giant leaf of 4 m, that withered in autumn 2002. At the end of January the tuber was repotted and reached the spectecular weight of 78 kg. On the 14th of March 2003 the bud became visible and broke the soil surfcae in its 1000 kg weighing container. On the 7th of May 2003 it reached the height of 78 cm and had a circumference of 58 cm. The final height on the 22nd of May was 274 cm!
The world record of a titan arum flower was held untill know at the Botanic Garden of Wageningen in the Netherlands, where it flowered in 1932 – some 70 years ago. The height of that flower was 2,67 m and we are excited to see that this years flower will produce a new world record. The Titan Arum is one of the most spectecular plants at all.  The plant naturally growns in the rainforests of Westsumatra. There were about 70 flowers in cultivation so far.
