Heather Honey and Beverages
CulinaryIn Scotland and Northern Europe, heather flowers are traditionally used to produce distinctive heather honey, which has a unique flavor. The flowers can also be steeped for herbal tea. [source]
Pollinator and Wildlife Habitat
WildlifeAlpine heather flowers provide abundant nectar and pollen for bees, butterflies, and other pollinators during late summer and fall when few other plants are blooming. The dense foliage offers shelter for ground-nesting birds. [source]
Harvest Tips
Alpine heather is not harvested for culinary use but is prized for ornamental value. Cut flowers for arrangements in mid-bloom; cut stems last longer than freshly opened flowers. For dried flowers, cut when blooms are fully open and hang upside down in a warm, dry location.
