I read where the spadix collapsed a very short time after it opened, I wonder if this is not another sign of something I have been observing in aroids in many species over many years. I have suggested that many Aroids (the genus Arisaema has taken this to the ultimate) will produce a smaller than usual bloom that, though it may have female flowers (in Arisaema the female flowers are NOT produced) , is never intended and in fact can and does not produce fruit/seed, the small bloom only contributes pollen to the genitic 'trail'. This might occur when a plant 'senses' that it is stressed (too many growing seasons without a tuber large enough to sustain the development of fruit/seed) or is growing in a site less-then-optimum to producing a large tuber which is able to sustain the length of time necessary for fruit/seed production.&nbs p; I was wiondering if some dissections could possibly be done to the remains of the female flowers on this or future small blooms to see if all the necessary parts are there which might indicate if these female flowers could ever develop seed. Just food for thought. Good Growing! Julius +More >Hi Julius, > >It was a baby at 1.33 metres.

A happy event indeed. Perhaps Dr. Hay (if he reads thsi) may be so kind as to try to determine from wence this plant came, if by chance from a Jim Symon seed collection? I`m sorry that you missed seeing this amazing bloom. Any details as to how tall the bloom was, etc.?? > > The Best, > > Julius Boos > > WPB, FLORIDA > > >Howdy All, > > > > >I found out on the news last night that Amorphophallus titanum is > >currently in flower in the Tropical House at the Botanic Gardens in > >Sydney, Australia.
