Cultural Significance
Ajuga has been cultivated in European gardens for centuries as a reliable, low-maintenance groundcover. Its vigorous spreading habit made it valuable for covering difficult areas where lawns wouldn't grow. The plant is beloved by pollinators, particularly bees and butterflies, making it important in wildlife gardening. While sometimes considered invasive in certain regions (parts of Maryland, Oregon, West Virginia), it remains a popular choice for challenging shaded sites.Shop Our Floral Collection
