In the fall the vine's leaves begin to die back, revealing long pods that contain numerous paper-thin seeds. Once vines are well-established, they will easily reseed themselves.
Hummingbird vines can become invasive in many areas if allowed to freely self-seed. You can help control them by collecting seeds each fall and pruning the vines back.
Seeds need to be cold treated before they will germinate, so if you intend to save seeds for the following year, place them in a glass jar and keep it in the freezer or outside over winter. You can start new vine indoors 4-6 weeks before transplanting, or sow them directly in the ground after danger of spring frost has passed.
