I agree this vine does not require full sun but it does like some or part day sunlight. I find it great for forest edges or where the morning or afternoon sun shades the area part of the day. I did some research and wrote a blog post on the vine at http://seaberry-hippophaerhamnoides.blogspot.com/2015/03/how-do-i-tell-sex-of-schisandra.html I found it very interesting that the plant, depending on growing conditions produces both male and female blossoms. Often they are sold as one or the other but it seems not to be the case. This particular plant you may want to have individuals in varying locations to encourage one or the other flower.
I take a few of these berries daily, maybe six. Dried.
Helps me cope with life.
The sensation I get from them is funny- it's all from the neck down. Caffeine makes me ambitious, restless, enthusiastic, agitated, angry... but schisandra doesn't feel like it's doing anything to my mind or feelings.
Just gives me that "ready to work" state in my body. You know, where you're warmed up, you've got a handle on the task, you're just a little way into it, and you know you've got the whole thing under control? (Again, physically, not mentally.)
That's what schisandra does for me.
