SS, I hope your Liberty like their new home!
Liberty is one of the hostas that grows happily in sun, and I'm not sure but I think they may whiten more (or perhaps earlier?) when they get more sun - our whiskey barrel has sun more or less all day, and the hostas were very happy and the white bits very white; in the border where I've moved them it's much shadier and the colour isn't as bright. Perhaps Ann knows?
