Temperate Climate Permaculture: Permaculture Plants: Goji Berry ...

The small Goji Berry is the "new" superfood.


Common Name: Goji Berry, Wolfberry
Scientific Name: Lycium barbarum, Lycium chinense
Family: Solanaceae (nightshade)

Goji Berries are only 1-2 cm (0.4-0.8 inches) long.


Description:
Goji Berry (Wolfberry) plants are medium-sized, deciduous shrubs with small purple/blue flowers that produce small  red fruit (1-2 cm).  There are two very closely related species (Lycium barbarum, Lycium chinense).  I have had dried goji berries on a few occasions.  They remind me of raisins.  They have a bit of a nutty flavor reminiscent of a tart dried cherry.  I have also had goji berry juice (it was blended with apple juice), and it had a rather tropical flavor to it.  Quite good.

Lycium barbarum 

From the book by Prof. Dr. Otto Wilhelm Thomé Flora von Deutschland, Österreich und der Schweiz 1885, Gera, Germany

History:
Goji Berries, Wolfberries, Matrimony Vine, Red Medlar, Duke of Argyll's Tea Tree... all names used to describe this plant over many years.  Recently, it has become known as a "superfood" due to its high antioxidant levels, but it has been cultivated for thousands of years around the world, especially in China.  Even though it is a "new" plant to the western world, it was grown as early as the 1700's in the UK.

Trivia:

  • Named the "Wolfberry" likely due to confusion about the scientific name... "Lycos" means "wolf" in Greek.  "Lycium" means "originating from Lycia", a region in modern day Turkey.
  • It is said that if held in the hands for too long, the fruit can oxidize and develop black spots.  It may just be that the fruit bruises easily.
  • Are fairly wind and salt tolerant.
  • Are fairly drought tolerant one established.
  • Recently ranked number one on the ORAC (Oxygen Radical Absorbance Capacity) Scale... used to rank foods with the healthy antioxidants (compounds that destroy free radicals that cause cancer and aging).
  • Some reports that it may interfere with the metabolism of warfarin (Coumadin) and make the blood more "thin", i.e. increase the risk of bleeding.  However, this should not be an issue for a person not on this medicine.

Dried Goji Berries is likely how we will see if for sale.  

We'll need to grow it ourselves if we want them fresh.
