Hey Welcome Aboard fellow New Yorker!!
We're glad you found us...
I have
Hollyhocks, and the dried
seed would normally fall to the ground just about now, and
then take root now.. *and then come
spring time,
will send up the main stalk for the
flowers*
(they are a biennial and will send out roots and leaves the first year, then send up
flower stalks the next year)
So, I would do them now..
*You can do both too if you want..
save some and
plant them in the
spring and then you will always have one's coming up..*
Try planting them several ways too, to see which is easiest for you...
I take the stalks and just shake on top of some freshly raked dirt *no grass or anything on top of the soil*...
and then I also
plant some on top of some regular garden soil in some 6 pk containers...
and then leave them on the ground, and the snow
will cover them up...
See which way is easiest for you and the
seeds...
or bad 
on how they came out... That's how we all learn 
...
