What you propose is easily accomplished with many Arisaema species to
reduce the time from seed until first flower to within two years. I
think this is very possible for Erythronium as well, but one concern
is not knowing how long to maintain the bulbs at warm temperatures
after the leaves die down before beginning vernalization. Given the
natural range of E. multiscapideum (PBS wiki lists as E.
"multiscapoideum"), there is a possible minimum time requirement for
warm dormancy, which likely varies with temperature, before the bulbs
can perceive vernalization. While there is some literature on this
topic for other species (especially Lilium), I can't find any
dormancy info for Erythronium. As for vernalization, ten weeks at 5C
has been reported to be the optimal vernalization period for
Erythronium 'Pagoda.'
