Update on the Arisaema sikokianum, I planted them 2 years ago and saw no
evidence that they had survived. Just last week I was doing some cleanup in
the area where they had been planted and found that they were coming up in
two places where the very small seedlings were planted and one shoot where
the full size plant had been planted. They are all very small so far but
there is the hope that they will continue to grow and become mature plants.
I am thrilled.
As to the pot grown plants they are in very good potting soil not my native
clay garden soil and probably do have better drainage, the ones in the
garden are on an incline so water does not pool there.
