I got my hands on a branch of Bittersweet this year and recently read about how you can grow them from seed. The bright-showy seed pods are what makes Bittersweet so unique and desirable.
How to Grow Bittersweet from Seed
Step One: Pull off the seed heads and let them dry out for 2-3 weeks. 
Step Two: Break apart the berries and split open to remove inner seeds. 
Step Three: Leave inner seeds to dry out for an additional week.
Step Four: Place some peat moss in a plastic bag and moisten it slightly. Place the seeds in the bag and put the bag in the refrigerator for three months. This allows the seeds to go through a dormancy period before starting to germinate in the spring.
I will provide an update in about three months! Have you grown Bittersweet from seed?
