Cardiocrinum: from Deno back to reality

Norman Deno's work on seed germination was conducted under controlled
conditions, and he usually did not attempt to get the resulting plants
out into the garden. Indeed, I once heard him tell someone at a meeting
that "you can't say you're growing something until it's self-seeding in
your garden." I checked to see what Edward McRae's book "Lilies" has to
say about treating seedlings with delayed hypogeal germination (the
pattern also seen in Cardiocrinum), and he assumes that the foliage is
emerging in spring, growing through summer, and planted out when dormant
in autumn.
If Garak has enough seedlings, it would be worthwhile to try to to
restart some into growth now, while putting the rest in cold storage in
barely moist peat until next spring. I've not grown these plants with
artificial cycles, so I don't know what the results will be.

Hi List,
after several 3 month cold / 3 month warm cycles on wet paper (5 if i
remember correctly) , I finally got some Cardiocrinum giganteum to
germinate at the end of last November. They spent the winter in the
house under lights, and now the leaves died down - the bulbs below are
intact and bigger than I thought judgeing by the tiny leaves. Outside
it's late spring, so what am I supposed to do? simulate another winter
in the fridge or try to put them out in the open? How much winter will
they need? another 3 months and it's August, so the next growing phase
may be shorter than this last one unless I give them another stay in
the house?
All that speed gaining theory from Deno-Cycles sounds good on paper,
but how am I supposed to ever get them in sync with the world again?
