I've killed several A. griffithii in the past couple years.  A few pots i=n
the cool greenhouse produced one bloom and two rotted tubers.  After
blooming, that one also rotted away.  Two others were planted outdoors in
the ground, in a mass of sugar maple tree roots in my little woods.  I
haven't yet seen any sign of them since planting them.  At this point, I'=m
0 out of 5 on griffithii.

One A. sikokianum has come back three or four years and bloomed each time=,
planted in the same little woods but on a bit of slightly higher ground,
near the base of a spindly Douglas Fir.  I have not had the courage to tr=y
sikokianum anywhere else so far!

A. candidissimum has not survived here beyond one or two winters when
planted at the edge of my little patch of woods.  A. consanguineum is
surviving around the edges of this woods.  A. serratum survived two winte=rs
in the woods, then disappeared.

I'm afraid my climate here is neither mild enough nor dry enough for some
of these borderline hardy Arisaema species.
