How To Grow And Care For A Giant Hogweed Plant

If you're an avid gardener, you've probably seen many beautiful and interesting plants in your lifetime. But have you ever come across a plant that you should absolutely not touch? Meet the Giant Hogweed (Heracleum mantegazzianum). This beautifully dangerous plant can cause severe burns and even blindness if touched.

Plant Attributes

Giant Hogweed is a biennial plant that originated in the Caucasus Mountains of southwest Asia. It can grow up to 14 feet tall and has a thick, hollow stem with dark reddish-purple spots and large, deeply incised leaves that can span up to five feet in diameter. The plant produces a large inflorescence of white flowers that can reach up to two and a half feet in diameter.

While Giant Hogweed may look beautiful, it contains a toxic sap that can cause severe burns when exposed to the skin. The sap contains a chemical called furocoumarin, which makes the skin extra sensitive to sunlight. When the sap comes into contact with the skin and the skin is then exposed to sunlight, a severe burn can occur. In some cases, the burn can even cause permanent scarring.

Plant Care

Due to the dangerous nature of the Giant Hogweed, it is not recommended to plant it in your garden. However, if you do happen to come across one in the wild, it is important to avoid touching it as much as possible. If you do come into contact with the sap, immediately wash the affected area with soap and water and cover it up to avoid exposure to sunlight.

Because of its invasive nature, Giant Hogweed is illegal to sell in some countries, including the United States.

Pruning

As mentioned, it is not recommended to plant Giant Hogweed in your garden. If you do happen to come across one in the wild, it is best to leave it alone and let it grow naturally. Attempting to prune the plant can release its toxic sap and cause harm to both you and the surrounding environment.

Propagation

Giant Hogweed can reproduce by seed, which can be carried by wind and water to spread the plant to new areas. It is important to properly dispose of any seed heads or plant material to prevent further spreading of the species.

Potting & Repotting

Since Giant Hogweed is not recommended for growing in a garden or pot, there is no need for potting or repotting information.

Common Pests & Plant Disease

Although Giant Hogweed is not susceptible to many common pests and diseases, it is considered an invasive species and can outcompete native plants in its environment.

Common Problems

The primary concern with Giant Hogweed is the risk of coming into contact with its toxic sap. It is important to avoid touching the plant and to wash your hands thoroughly if you do happen to come into contact with it. If you experience any symptoms such as blistering or burns, seek medical attention right away.
