  Rafflesia flower size
From: bonaventure at optonline.net on 2007.01.23 at 18:52:39(15115)
Regarding the size of the flower of Rafflesia - is that a single bloom or an inflorescence, such as an Amorphophallus or other aroid, or more relevent, a Pointsettia? Euphorbs have a cluster of inconspicuous flowers often surrounded by showy bracts. There appear to be individual small flowers within the center of the "bloom" in the photographs I had examined. Is there possibly any truth to this? What is the largest (individual) flower in the plant kingdom?

Dear Bonaventure Magrys,

to my humble knowledge, it is the largest single flower in contrast to
the largest inflorescense of Amorphophallus titanum.

But let's hear one or more of the professional botanists here.... ;-)

Good growing,
Bernhard.

Maybe Selenicereus grandiflorus?

Or maybe Victoria amazonica?

i'm not a botanist, but it's my understanding
Rafflesia has the world's largest single flower.

the largest inflorescence apparently is produced by a
palm tree, not Am. titanum (but titanum has the
largest unbranched inflorescence).

"Largest flower" is a question that seems to interest even people without our
addiction. I've read the following several places:

largest single flower - Rafflesia arnoldii
largest unbranched inflorescence - Amorphophallus titantum
largest branched inflorescence - Corypha umbraculifera (talipot palm)

although I've also seen Puya raimondii, one of those incredible Andean
bromeliads, as a contender in the last category. The inflorescence is in the
same size range (6-10 meters), but the palm seems to win on flower count by
a couple of orders of magnitude (and probably on total weight, too).

Of course, seeing it several places may just mean most of the writers copied it
from the same original source.

I think the largest inflorescence belongs to Agave americana (up to 12 m)

forgot to mention, if you are interested in some great
shots of the inside of this flower, you should check
the attenborough book, i think it's called "the
private lives of plants."
