Kidney vetch is a medicinal plant native to Europe. One of its nicknames is woundwort, which refers to its capacity to help heal wounds. The flower looks a lot like a clover, but then usually yellow and more robust. It only blooms a couple of times in its short life. The plant itself is covered in silky white hairs. For the Dutch dunes, it is a relatively rare flower. Whether or not it will grow in the dunes depends upon the weather. The seeds only germinate under specific weather conditions. Kidney vetch grows in massive numbers where the coast is expanding, among marram grass on the sheltered slopes of the beach ridge.
