Hosta, they probably won't flower next year, what are plants called that take two years to flower, Bi annual is it?
I would think at that size they would be safe and better planted out. Those of mine are now about five ft tall, planted out last Autumn, but I lost quite a few in the winter. They will be about 8/10' next year with the blooms. Just put lots in, then if you lose a few it won't matter, and if you have too many you can pull them out.
When they self seed, leave them in, they seem to be tougher growing like that.
