Re: [Aroid-l] Amorphophallus Titanum offset?

Hi Bernhard,
One of the plants that we donated to the Marjorie McNeely Conservatory at
Como Park in St. Paul had two leaves on it at the time. When they
unpotted it after dormancy set in, there were two corms, one smaller than
the other. The larger one, BOB flowered, then died from the effort
(the inflorescence was small and distorted, and the plant apparently went
into the flowering stage too early). The second separate clone
(BOB, too - not the second corm of the first clone) might flower within
the next few months (it's dormant now, after producing a large leaf that
lasted for over a year).
Here are links for some photos:

Hi Brian,
when you write 'split into two corms' would that mean that a
relatively
big tuber would have split into aprox. two tubers of the same size?
Or was it what we would call an offset, e.g. a small tuber grown from
a
bigger one?
You might remember the 117 kg tuber at the Bonn Botanical Garden
that
grew a triple inflorescence. This tuber grew three leaves
threreafter
and grew three individual tubers in the vegetative phase after the
triple flower.
Happy offsetting, Bernhard.

the
original Symon collection.
