I have a 2 inch seedling of Stellera chamaejasme, growing well in it's own pot. What shall I do with it? One of the suggestions I've had is to winter it over and then plant it out next spring, and someone else told me to plant it out in the early fall. It's taken two years to get one seedling to germinate, survive and grow, and I hate to think I'd kill it before it had a real chance. It's one of the plants that I've had on my 'want' list for years, so help me out, please.
