Codonopsis rotundifolia var. angustifolia
This twining climber is one of our favourites with green bells covered in fine dark red lines and faint bands of pale red. Even the calyx has radiating fine red lines. Inside there is a circle of dark red dots and a scalloped line lower down. The leaves are larger and more pointed than its cousins with a toothed edge.
This species is often misnamed C.tangshen in the nursery trade and consequently in seed lists.
The seed is fine and reddish brown.
