Arisaema and Fritillaria

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.

Hello Anita and Ben
For the disappearing Arisaema I still don't understand if you planted
dormant tubers or actively growing plants of A. sikokianum in late summer.
As I have never been able to grow this plant myself I don't know how long
it's growing cycle is. Dormant Arisaema tubers lose their roots completely
unlike many other geophytes so will not settle in a new environment.
Somehow your growing conditions of the pot grown plants must differ from
open garden culture, is it drainage?
Thank you Ben for your remarks on the tetraploid Fritillaria. But tetras
do at least bear some fertile seed in general or am I wrong?
Is the Dutch commercial stock of this bulb only propagated vegetatively?
It is so strange that all my other F. Imperialis never set seed and this
one does but without any germination.
Thank you and bye for today
