Heracleum persicum


Heracleum persicum, commonly known as Persian hogweed or simply hogweed,Golparگلپر , is a polycarpic perennial herbaceous flowering plant in the carrot family Apiaceae, originally native to the region of Iran. It grows wild in humid mountainous regions in Iran, as well in some adjacent areas. As a spice, its common name in English is 'angelica,' although it is not related to the genus Angelica. Having been introduced in the 1830s, it has spread across Scandinavia. It is now very common in northern Norway, where it is known as the Tromsø palm.
The plant has also been spotted in Sweden. In Finland, it has been declared as invasive species.
Persian hogweed is a polycarpic perennial, that is, a mature plant flowers and bears fruit season after season.

Uses

Food uses

The seeds are used as a spice in Persian cooking. The very thin, small seed pods are aromatic and slightly bitter. They are usually sold in powdered form and are often erroneously sold as "angelica seeds". The powder is sprinkled over broad beans, lentils and other legumes, and potatoes. Golpar is also used in soups and stews. It is often used sprinkled over pomegranate arils. Golpar is also mixed with vinegar into which broad beans are dipped before eating.
Golpar can be used in small amounts when cooking beans to reduce the effect of gas in the digestive tract associated with consuming beans.
In Persian cuisine, the petals are used in the spice mixture advieh to flavor rice dishes, as well as in chicken, Fish and bean dishes.
The tender leaves and leaf stalks can also be pickled.

Public health and safety

The sap of the Tromsø palm contains furanocoumarins, which in combination with ultraviolet light, leads to phytophotodermatitis. There is some anecdotal evidence that H. persicum may be less dangerous than H. mantegazzianum with respect to phototoxicity.

Control measures

Known ways to fight Tromsø palm are the constant cutting of new shoots. When cutting down, protective equipment is recommended, and metal cutting tools should be cleaned after use because the juice is oxidizing.
