Dear Fred;
This is as good a time as any to transplant Lycoris. Be
careful and try to not disturb the roots.
They can be transplanted almost any time while they are
dormant, depending on species, from June 1 to end of August.

The true species has become uncommon in commerce, but is
regularly offered by Plant Delights and Fairweather Gardens
nurseries. Both can be googled and it may be best to inquire if they
are not listed this year.

It should do just fine in the Boston area. Jim W.

ps Incidentally bulbs purchased dried out in Oct November have been
severely stressed and there are survival problems. If they survive
they may take 3 or more years to recover and bloom.
and
They prefer a moist shaded spot.
