A hardy Mediterranean herb with wrinkled, woolly gray-green leaves and small white flowers in dense clusters. Traditionally used for herbal tea and medicinal purposes, it thrives in poor, dry soil with minimal care.
Why grow it
White horehound is notably more cold-hardy than many Mediterranean herbs and tolerates neglect better than culinary alternatives like oregano or thyme, making it useful in marginal sites. It establishes readily from seed and requires no fertilizer or supplemental water once established, distinguishing it from herbs that demand richer soils or regular irrigation.
Watch out for
The plant can spread vigorously by seed in favorable conditions, so deadheading spent flowers before they mature helps contain it. Harvesting foliage is best done before flowering to capture peak volatile oil content, though the plant tolerates repeated cutting.
