Heather turns fields purple in the summer. It is the dominant species in the heathlands of the northern Dutch dunes and on high sandy grounds more inland. By the time bog heather has flowered, common heather starts to blossoms. It takes 3 to 4 years for a plant to flower. And after 15 years, it becomes very woody and flowerless. Common heather is an important plant for insects that consume nectar and pollen, such as mining bees, butterflies and moths.
