Pygmy willow is believed to have survived for several thousands of years by the side of the big ocean. This little willow plant put down its roots on Golta at the end of the last Ice Age, along with other alpine plants. The others buckled under when the climate grew warmer, but the pygmy willow survived. On the weathered rocks that stick up from the moors on Golta, the growing conditions are much like those in the high mountains.
This plant creeps along the ground and is well suited to this harsh climate with its short growing season. It is most common in the high mountains in places where other plants meet with problems because of longterm snow cover - they thrive best where there is no other sturdy vegetation. In the lowland, pygmy willow is easily out-competed by other plants. But, when there is neither forest, moor nor grass to win over from this little creeper, the pygmy willow can make a living also here.
