Face Front - not

[Susan Cox]

George, your statement must be the one I recall reading last summer or
so.  This is what made me
think of watching the bloom.  Not only did the bloom not twist to the
light, but neither did the leaf.
Only the peduncle and petiole moved by bending toward the light, so once
the bloom and leaf have
emerged, light doesn't affect their direction, neither on their stalks,
nor to the sun.  Only the stalks
attempted to get the leaf and bloom closer to the light.   This also
meant that the leaf never changed
position in relationship to the bloom.  I thought this was particularly
interesting because some blooms will twist off the plant, trying to face
the sun.  I turned this pot in every direction you could imagine, and
they didn't twist.  Maybe this plant is just uneducated.

>A few years ago I took a survey of the direction all my Arisaema
triphyllum were facing - N, E, S, or W. There was no statistical
significance of preponderance in any direction.<

I guess if anyone wants to see the bloom facing any particular
direction, the plant will have to be planted  in a  pot that can be
manually turned.  That'll teach 'em.  At least once they're up, they
can't switch on you.  Nina, did your plants change direction before they
became stabalized?

Thank you everyone who had something to add to this.
