The olive tree is present on earth since prehistory !!!
It likes our Mediterranean climate where summers are hot and dry , winters are mild and wet .
It needs the sun for fruit ( olives) , some water in summer, stony soil
It can live up to 2000 years old, I remember a beautiful specimen in tree nurseries Pierre Basset Grimaud .
It supports cold until -15 ° .
Its fruit , the olive is a drupe . It ripens in the fall or early winter . it varies from green to brown as and when it evolves .
In Western culture , it is a symbol of peace .
