Inula helenium seeds grow into elecampane or horse heal — a large, imposing perennial herb native to the temperate biome from Central Asia west through Russia and Europe, now widely naturalised across Europe, North America and other temperate regions. Described by Linnaeus (1753). The genus name derives from Helen of Troy — legend holds that elecampane sprang from the tears of Helen as she was carried off to Troy. The root has been used in herbal medicine for thousands of years — for respiratory conditions (cough, asthma, bronchitis), digestive complaints and as a tonic. Contains inulin (named after Inula) — a prebiotic dietary fibre. Produces tall stems to 1.5–2 m with large, velvety leaves and brilliant golden-yellow daisy flowers to 7 cm across.
