I haven't done candytuft either. But I think it's one that's considered "easy" by most who have wintersown it, meaning it sprouts and grows well.
Remember, it's still early! I almost never have wintersown sprouts of any kind until March. This is just such a warm, weird weather year that wintersown things are sprouting early. From reports I've seen, most seem to be zone 7 and warmer.
