With regards to the excellent discussion on the factors that can
affect flowering in Amorphophallus titanum, I would like to add that
there can be individual genetic differences that can influence
blooming as well. Here's a recent picture of me with an 8 year old
plant of Amorphophallus titanum that I grew from a seed obtained from
Tito Wee. Tito's seed came from one of the original plants that also
came from seed that Jim Symon first brought from Sumatra over 15
years ago. So the plant in this picture is the result of a sibling
cross from two of Symon's original plants, a second generation if you
will. I have other sibling plants that are not more that a meter
tall showing great variability within the population. This
particular plant growing in a 133 liter pot (35 gallons) should bloom
after the next dormancy later this year, or early next year. My
sincere thanks to Randy and Ty Strode at Agri-Starts, Inc., Apopka,
Florida, for letting me keep the plant there in their state of the
art greenhouse for the past two years as it definitely has now out
grown the screened in pool area at my home in Vero Beach. Thanks to
the expert grower's care at Agri-Starts we should see a bloom within
the next year.
Regards, Scott
