28 sie 2018 · Hogweed is an extremely successful invader in part due to its prolific seed production and growth rate. These attributes coupled with its large size allow giant hogweed to significantly alter natural environments and plant community structures.
Anyone who suspects they have found Giant Hogweed should take photos, check online to compare the plant to giant hogweed photos, and then contact a Virginia Cooperative Extension agent.
The density of populations of Giant Hogweed may also vary considerably. In large areas of the plant, density may range from sparse growth (1-3 adult individuals/10 m2) to dominant stands in which Giant Hogweed occupies almost the whole ground area (more than 20 adult individuals/10 m2).
Common names: giant hogweed, giant cow parsnip, cartwheel plant, the Hog. Scientific name: Heracleum mantegazzianum. Family: Apiaceae. Habitat: derelict gardens, neglected urban places and waste ground, on rubbish tips, roadsides and by streams and rivers. Flowering season: June and July.

Owing to its height and rapid growth rate (it can reach 4–5m in height), Giant Hogweed can suppress all plants other than trees and shrubs, mostly through shading them out. Dense stands can also restrict access to amenity areas and riverbanks and reduce sightlines on roads.
Giant hogweed is one of the most hazardous invasive plants found on PEI. Its spread has negative ecological, economic, and health effects. Giant hogweed certainly earns its name. Its colossal size, growing taller than humans, allows a single plant to occupy a large area, easily crowding out native species for space and light.
