25 JERSEY GIANT ASPARAGUS CROWNS/ROOTS, 2 YEAR-OLD

I'm in zone 8 in e. texas. temps will probably drop into the mid 20's this winter. i hear that these are dormant crowns. safe to plant deeply now?

I'm trying to decide when to order these. i'm in zone 6 just north of nyc. built raised beds for this, but haven't planted asparagus yet. help?

I am in the piedmont region of sc, is late may too late to plant these crowns in my area?

I did not realize these are shipped out of china. mine were shipped over a week ago and no sign of them anywhere. will plants be healthy?
