Marshmallow (Althaea officinalis)
Regular price $19.95Soothing 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 treat we know today—but its roots have a much longer history in traditional herbalism, where they have been valued for their soothing qualities and traditionally used to support the respiratory and digestive systems.
The plant features velvety leaves and pale pink, hibiscus-like flowers that attract pollinators and bring gentle beauty to herb gardens, cottage borders, and apothecary patches. Its roots, leaves, and flowers have traditionally been prepared as teas, syrups, and salves and used for soothing sore throats, coughs, and minor skin irritations. Marshmallow grows best in moist, well-draining soil with full sun to part shade and is a beautiful addition to medicinal gardens, wetland edges, and temperate food forests.
