In a friends garden there are 2 flowers of arisaema candidissima from
one "clump". The larger faces the wall, away from the lawn, the much
smaller flower faces the lawn. If they come from still linked tubers
then that may be influencing the direction.
I have a range of sizes of A. fargesii in leaf, although only 1 flower,
and it is the different leaf shapes that appeal to me, from dinner plate
sized entire leaves to divided leaves with separate lobes either side of
the stem, and some in between.

Brian Whyer, Buckinghamshire, England, zone ~8, but cool and raining
today.
