All my spice bush is growing, natively, at the edge of the woods which spends half the day in shade. I have a section of woods that is total shade all day and noticed, while mowing lawn the other day, that a whole bunch of them have started coming up there too. I'll bet I have, at least, 25 or 30 of them and some are very large. They aren't as tall as in your picture--maybe 6 feet tall or so but very wide.
