Grossanne combines everything you would expect from an olive in Austria. Large fruits, from a tree that endures the lowest temperatures.
There is evidence that many trees of this variety survived the icy winters of the 1950s in southern France.
As usual with the French, they don't really want to. Compared to our weed olive, the Italian “Leccio del Corno”, the root growth is very poor and it takes one to two years for the seedling to get moving, but then the joy is great.
A partner tree is not absolutely necessary, but Grossanne is happy about the company of Bouteillan and Aglandau.
