Thank you so much! The flower is called Gederams (Chamaenerium angustifolium), a common weed in Denmark. In English it's called 'Rosebay Willowherb' or 'Fireweed'. In German 'Wald-Weidenröschen'. The roots and shoots are edible. This one was growing in the industrial district in Aakirkeby. Its habitat was being destroyed by the construction of a new parking lot, so I took it with me :-)
