I order from Gilbert Wild pretty much every spring, have never seen a difference in how they grow. Also planted a few itohs last spring that were sorta potted (mailed not quite bareroot from that PA nursery that a few of us got those Plantek ones from) and they did fine, just like transplanting any other perennial. Is it my preferred time to plant? No, they will need more water and care than those last planted in fall, but I won't pass up a root that I really want because it's available in spring rather than fall.
