Our plant this week is the most abundant plant on Earth, so common it grows almost everywhere, with varieties even growing in the Arctic. The Poaceae (Grass) family has over 12’000 different species which include cereal grasses, bamboos, natural grasslands and cultivated lawns. Grassland (habitat where grass is predominant) cover approximately 41% of the Earth’s surface. Grasses also play an important role within the vegetation of many other habitats, including wetlands, woodland and forest.
