Yes Judy
My 12 or so tubers range from pea sized off-shoots to flowering sized
plants. Only the actual flowering tuber has completely divided lobes,
although 2 other partly lobed, and 1 still entire leaf, are in fact
slightly larger in overall dimensions. Maybe the flower is taking its
toll on the available nutrient levels.
I find fargesii much more tolerant of pot growing than candidissima. The
latter invariably rots off the main tuber and leaves me with just the
off-shoots if it gets the slightest bit too damp too early. At least
that is my theory. I am open to suggestions to improve my percentages
with candidissima in pots. In the garden I don't have enough experience
so cannot compare. A few years back there were a number of candidissima
planted out and in flower at RHS Rosemoor in Devon, on a bank under an
oak tree. There were few left the following year(s), unless I happened
to miss them on my occasional visits. The rainfall is quite high there,
but there are large numbers of other arisaema in more wooded areas
within a 100yds or so.
On the orientation issue, what happens when you plants them either side
of a path? Do they ignore one another and pretend they are alone? :-)
