Marshmallow

Perennial to Zone 4. Cousin to the hollyhock, used to soothe and soften irritated skin and membranes and to relieve stuck hacking coughs. Also mildly stimulates white blood cell production and relieves urinary tract infections and prostate problems. Enjoy the attractive flowers of this showy 4–6' plant through the summer or eat the velvety leaves in salads. All mallows contain soothing mucilage in the root, and marshmallow has the most, so it makes a great home-garden substitute for slippery elm. Harvest roots in autumn of the third year. For tea, steep roots in cold water for several hours rather than boiling. Plant in cool moist soil. Will self-sow. About 350 seeds/g.
