Vitis coignetiae

Vitis coignetiae

Vitis coignetiae or Crimson Glory Vine is a climbing shrub with large leaves that turn orange and red in the fall.

Its growth is exuberant and it needs a lot of space to grow. A little trellis will not suffice.

Original from north-east Asia, it is hardy.

Description:

This is a very vigorous vine. New shoots are tinted purple. It climbs by winding around obstacles, so support must be provided in the form of wires or a net.

The leaves are 15-30 cm in diameter. They are simple, rounded, toothed at the edges, with deep petiole sinus. They are green but turn orange and red in autumn.

The flowers appear in clusters. They are small and green.

Edible fruits appear in large grapes and are black at maturity.

Use:

  • Food: fruit was used to produce an alcoholic beverage and is currently used to produce wine.
  • Ornamental: the vine is grown for its very large leaves and autumnal colors.
  • Medicinal: used in traditional Korean medicine to treat inflammation and cancer.
