Woodland Angelica

With summer fast approaching, more invasive plant species are popping up. One species that has become quite common is Woodland Angelica. This invasive plant is a large biennial member of the carrot family, growing 1-2 m tall and flowering from July to September. Its leaves are pinnately compound and leaf-sheaths are enlarged. Leaflets are ovate and often lobed, with toothed margins. Flowers are small, fragrant, white to pale-lilac, and borne in an umbel (umbrella) formation on thick bamboo-like stalks with purplish joints. It is known to be a prolific seed producer.

Woodland Angelica usually grows in open areas with damp soil including ditches, hedgerows, marshes, fields, and woodlands. It is tolerant of full sunlight, full shade, and drought, but not usually tolerant to acidic conditions. It can dominate disturbed habitats due to its prolific seed production and ability to shade out competitors. It is strongly attractive to pollinators and may divert them from using native species. The sap of Woodland Angelica contains chemicals which can cause rashes and burns when in contact with human skin.

If you identify Woodland Angelica on your property, physically remove first year plants and cut the seed heads of second year plants to stop the spread. It is recommended to wear gloves, work on cloudy days, and wash thoroughly after handling to avoid burns and rashes. Do not compost or burn plant or plant parts, instead double bag them and let them rot in the sun before discarding.

Woodland Angelica was first introduced to North America by French settlers in the 1600s or 1700s, and now grows over much of Nova Scotia. Woodland Angelica is commonly mistaken for Giant Hogweed, another invasive plant that causes severe burns when its sap comes in contact with human skin.
