In Northern Norway many montane plants grow down to the sea level. Last summer when I visited Andøya (70oN) for a week. Saxifraga aizoides was common almost at the beach. In Southern Norway it follows streams and rivers down to the coast some places. The yellow form is the commoner but orange or almost red forms exist too.
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
