The olive tree is a plant of character and has a 5,000-year history:
The olive tree (Olea europea) presumably originated around 3000 BC in the region of today’s Syria/Palestine/Israel through the cultivation of two species growing in the wild. After that, the plant slowly spread throughout the entire Mediterranean region. Olive saplings were planted in California and Argentina during the Renaissance. The cultures in South Africa and Australia are even younger.
The olive tree is considered to be extremely robust and can live up to 2,000 years. It reaches its full yield capacity just at about age 15. It is content with barren soil and endures temperatures as low as minus 8 °C. Green and black fruits stem from the same tree. Young fruits are green and turn red, then purple and finally black with increasing maturity.
