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.
