Purple-stemmed angelica (Angelica atropurpurea) is a majestic tall perennial that can reach heights between 1.5 and 2.5 metres. It is characterized by its robust, deep purple stems and large umbels composed of small white or greenish flowers, visible in late spring and early summer. Its leaves are broad, divided into serrated leaflets, and can measure up to 60 cm in length. This plant thrives in moist, organic-rich soils, commonly found in wet prairies, swamps, and along waterways. It prefers sunny or partially shaded locations. Hardy and resilient, purple-stemmed angelica tolerates Quebec's winters and grows naturally in areas where soil moisture is consistent.
Medicinal and Culinary Uses
An herbal tea made from the leaves of this plant is used as a carminative and stomachic, relieving colds and rheumatism. Its seeds and roots, which are more potent, are similar to those of angelica (A. archangelica), although less aromatic. The root has carminative, diaphoretic, emmenagogue, sedative, stomachic, and tonic properties, and is used to treat fevers, gastric disorders, obstructed menstruation, and as a female tonic. For external use, it can be used as a gargle for sore throats and as a poultice for wounds and swelling, also treating rheumatism both internally and externally. All parts of the plant can be consumed raw or cooked. Fresh or dried young leaves, as well as seeds, are aromatic and can add flavour to dishes. Fresh stems harvested before flowering can be candied or eaten raw like celery.
Ecological Role
Purple-stemmed angelica plays a crucial role in Quebec's wetland ecosystems. Its large flowers in umbels attract a variety of pollinators, including bees, butterflies, and even certain beetles. The hollow stems also provide shelter for small insects. Additionally, this plant helps stabilize moist soils with its dense root system, contributing to the protection of shorelines and riparian habitats. Purple-stemmed angelica promotes biodiversity in wetland areas by providing essential habitat and food sources for pollinators and other local species.
Purple-stemmed angelica seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
