Yes, theres good advice on Phil's website, Jenna.
They should produce stalks next year, but the size of the stalks may depend on the size of the crown.
Ive read that large crowns should be divided into lumps about the size of your fist, so that seems to be a good size for producing something for next year.
Ive kept one in a pot overwinter for a friends garden, but you have to tend to its needs. It produced small skinny stems in the pot.
Personally, I would plant the crowns you have purchased now, as I believe they will be happier and will develop better over early spring when in the ground.
If you are concerned, then how about planting the 3 biggest ones and put 2 in pots
