Well John, we im trying it. Some word are near the same than in english or german so i can understand some sentences. ;)

Back to Bergen:
There are 70 more raindays then in germany, much more wind, less sun hours and 10°C colder average T in Summer. So Yuccas, Trachys oder Ficus Carica cannot grow well. The best average for them is 15-25°C, sun and in summer water, not in winter.

Here are some Statistics:

Only January and December are warmer in Bergen. They have more wind, more rain in cold winter so the felt Temperature is much lower. For Trachy ´s e.g. that is not an advantage. The best temperature for Trachy´s to grow is 15-25°C.

Ficus Carica will have much sun and warm summers, so they have it more difficult to grow in Norway. Also the dark times in winter are longer in middle Norway then in middle Europe.
