New Zealand Gorse


New Zealand Gorse is part of the evergreen shrubs family with a connections to the pea family Fabaceae. It is very common all over New Zealand and has become a troublesome weed. The plant has green stems and very small leaves. The leaves generally range from 1-4 cm long, with a variation in spininess. The flowers of all species of Gorse have yellow flowers. Interestingly, the flowers are said to have a coconut smell to them. The plant is native of Europe, but has been introduced in New Zealand as a decorative plant, but is now considered an invasive weed. It has spread rapidly because of its aggressive seed dispersal and is hard to get rid of. The plant also regenerates itself after fires, so it can withstand harsh environments. The shrub can cause severe damage because it is highly flammable, with an oily foliage and seed. It also thrives in poor growing conditions and requires little help from the environment to flourish. The Gorse is useful in nitrogen fixation; however. It can also provide cover for birds' nests and become food for other organisms. The plant is edible to humans as well, some people add it to salads and such. Unfortunately, in New Zealand, the plant is considered a problem. It has led to plant competition and is rapidly spreading all over the country.
