Hi Matthew,

interesting question, but also hard to answer in a not-haired, tubers form plant.
Amorphophallus is added complicating factor, that yes the tuber is replaced each year in part with renewable new tuber tissue, so that an age determination on the basis of the tuber is no longer possible.
When an individual bulb will be there probably instructed to records, that there will probably only in botanical gardens that can hold the plants under good conditions.

Then added that a genotype of a plant that makes Cormels is Yes theortisch immortal...

In Bonn, there is already a long experience with A. titanum, and some of the larger specimens are already there in culture.
Details about the age of one of the great titaum I by a gardener there once obtained and compiled from some Veröffntlichungen.

The plant or bulb, which in 2006 has brought the spectacular triple Blütnestand ( http://botgart.uni-bonn.de/o_samm/titan/titangal06.php ), goes back to the in-vitro propagation attempts by Prof. Kohlenbach with plants from the Palmengarten in Frankfurt/a.M..
1985 and 1986 Blattexplantate of two plants were removed and grown in sterile culture.
Three-flowered bulb of 2006 is a plant that is named Kohlenbach Explant 18/XIII probably at the 8.6.1988 in Earth was convicted and was donated to the Botanic Gardens in Bonn at the July and has flourished in the year 2000, then the first time; the plant has flowered (all three part of Tuberous of flowering 2006) then in 2003, 2006 and 2008; whether she has yet again flourished after that, I don't know, but I strongly believe, as I am assuming that the garden also didn't kill the plant or the three tubers of the genotype until today.

That would be a secure age by almost 26 years, plus one or two years in-vitro culture and actually also plus the age of donor plants, so that when removing the ex Plan Act of a 4 m high (1985) and 1986 had a smaller sheet.

If you titanum put to one of you, that is quite a long-term project...

Happy growing, Bernhard.
