Ramson
It is called Ramslök in Swedish but has many different names. Its Latin name is Allium ursinum but is perhaps better known as wild garlic, ramsons, or wood garlic. It is a relatively rare plant that is often found on foliage and in groves. Here in Sweden, it has about the same extent as the oak north.
I didn't think much more about this site until I saw a video of a Danish photographer I follow on YouTube. He published a clip in which he is out in a forest photographing a sea of white flowers. He calls them white garlic, but I recognized the leaves and realized that I had to go back to Borstbäckens Nature Reserve.
Next to the creek that winds up through the ravine stood ramsons in full bloom. In some places, a sea of white flowers and in others like white oases around a tree. For those who have the opportunity, it is worth visiting and bringing home some for the evening barbecue.
