Used in traditional herbal medicine to soothe and coat the throat and as a poultice to calm skin irritations. Also a beauty of a plant! Soft and hairy perennial stalks bear delicate, hollyhock-like, pale white-blue flowers with purply- red centers in late summer. All parts of the plant are edible. Attractive to pollinators.\nCold Stratification Required - See Growing Instructions for details.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Marshmallow-vendor-unknown-1630680501.jpg?v=1735579518","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Marshmallow-vendor-unknown-1630680503.jpg?v=1735579518"],"price":5.39,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:38.561Z"},"share_url":"https://firestarter.network/l/lst_TSG49fI4","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
