Also there may be many varieties there not available in the USA and viceversa. it may depend also on personal taste. I was not impressed by Black Mission, I liked Petit Negronne, but I appear to like better green figs with red pulp and crunchy seeds and fig flavor. Seems that here in the USA the dark ones with berry jam flavor and sweetness are the most popular. Maybe your friend could try 2 different varieties. Also I think the weather near Geneva might be relatively mild because of the lake and maybe the mountains protect it from the wind. It is not far from Torino Italy, although I wonder if being on the other side of the Alps may make a big difference ( Torino has foggy, humid winters with snowfalls.
