An Invasive Asian Beauty
On a trip this year to the Wicklow mountains, for a college field trip I stumbled across a monster that plagues many gardeners around the country. This beast from the orient is one of the most invasive alien plants in Ireland, Japanese Knotweed.
First Introduced in England as an ornamental plant, Fallopia japonica, quickly spread throughout the country and came to Ireland. Here it is found mainly along waterways and causes major problems by invading natural habitats. It has also known to cause damage to buildings and hard surfaces such as paths and roads with its roots.
When I first learned of the plant many years before as an invasive plant I never understood why people would want it in their garden. Seeing it in the dappled sun its beauty shone and I understood why people brought it from Asia to grow in their gardens. However then you look around and see the sheer amount of the plant and how it forces itself into its surroundings. It is a very vigorous grower, often out competing other plants around it for space, nutrients and water.
