Notes:

  • Rapid growth once established, spreads by vegetative and seed dispersal. Five-leaf Akebia can grow as a dense groundcover or smother trees and shrubs as it grows over them. Introduction and spread of Akebia is largely due to inadvertent human activities. Planting as a ornamental vine is common sources of garden escapes. This vine takes about 5 years to mature into a fruit bearing plant, though fruits and flowers are relatively uncommon.
  • On Nantucket, this species is known from a single site where it has been since the early 1990s. Plants have spread to the other side of the street , perhaps via mowing.
