Soothing Herbal Powerhouse with Soft Blooms and Silky Roots

Marshmallow (Althaea officinalis) is a medicinal herb and flowering perennial treasured for centuries for its soothing, mucilaginous roots and leaves. Native to Europe and Western Asia, this soft, silvery plant is the original source of the sweet we know today—but its true gift lies in its ability to calm inflammation, support digestion, and soothe the respiratory tract.

The plant features velvety leaves and pale pink hibiscus-like flowers, loved by pollinators and perfect for herb gardens, cottage borders, and apothecary patches. Its roots, leaves, and flowers are traditionally used in teas, syrups, and salves to ease sore throats, coughs, and skin irritations.

Marshmallow grows best in moist, well-draining soil with full to part sun and is particularly suited to medicinal gardens, wetland edges, and temperate food forests. This hardy perennial brings a gentle beauty and powerful healing energy to any space.
