Native to southwestern China. Grown in Europe as ornamental plant from around the 15th century. Alcea rosea is variously described as a biennial (having a two-year life cycle), as an annual, or as a short-lived perennial. It frequently self-sows, which may create a perception that the plants are perennial. The plant may flower during its first year when sown early. It will grow in a wide range of soils, and can easily reach a height of 2.5 m. Its leaves are large and heart-shaped.
Aukštoji piliarožė auginama gėlynuose beveik visame pasaulyje. Išvesta daug veislių su įvairių spalvų žiedais, kartais net dvispalviais ar trispalviais. Iš džiovintų žiedų gaminama arbata. Lietuvoje pasitaiko sulaukėjusių aukstųjų piliarožių sausuose šlaituose, pakelėse.
