Transplants in a field study had 53% survival after 7 years (Mottl et al. 2006). Wild ginger self-sows and has extensitve vegetative spread (Mottl et al. 2006), and once introduced spreads raplidly (Mabry personal observation).

Mature plants transplanted in the field had 70-83% survival after two years (Golay et al. 2013, Altricher et al. 2020), and continued high survivial in year 3 (Altricher et al. 2020). In addition, by year two new plants were establishing either by seed or vegetatively (Golay et al. 2013, Altricher et al. 2020).

Ant dispersed; low seed output; high vegetative spread (Barkely 1986, Gleason and Cronquist 1991).
