One of my all-time favourite plants in the high north: the cloudberry. The fruits look like solidified clouds and they can grow where almost no other plants survive, from nutrient-poor marches to wet and acidic heathlands. They can withstand temperatures as low as -40 °C and there they still stand, beautiful as ever.
And they are tasty! I often imagine them tasting like clouds as well, but not the boring white fluffy clouds, but tasty, dark, thunderclouds, rolling over the mountains late in the evening, with red edges from the setting sun.
I love them in yoghurt as well, but they are best as the occasional tiny snack on a strenuous hike to the alpine area.
