Giant Hogweed

Giant Hogweed (Heracleum mantegazzianum) is a close relative of cow parsley primarily from Southern Russia. It can reach over 3m in height. Even though this impressive plant can be appealing in some circumstances, many gardeners will want to destroy it as it is potentially invasive weed and the sap can cause very bad skin burns.

Himalayan Balsam

Himalayan Balsam (Impatiens glandulifera) is a relative of the Busy Lizzie, however, it reaches well over 6 foot, is an invasive weed and is a major problem, particularly on riverbanks and waste land, but can also intrude gardens. It grows quick and spreads fast, suffocating other plants as it goes.

Rhododendron Ponticum

Rhododendron Ponticum is an invasive weed that is extremely resilient to the harsh Scottish climate and has a high tolerance to shaded, low light conditions. This, combined with its high fertility, has enabled it to out-compete our native flora and thrive throughout the country.

Field Horsetail Glasgow

Field Horsetail

Field Horsetail (Equisetum arvense), sometimes called mare’s tail, is an deep-rooted perennial invasive weed that can spread very quickly to form a thick carpet of foliage, overcrowding less vigorous plants in borders.
