10 Surprising Facts About Grass

Grasses are often considered valuable for their aesthetic qualities, but there is much more to these plants than meets the eye. Here are a number of Facts About Grass some of which are surprising.

All grasses are in the Poaceae family, which is one of the most abundant families of plants on earth.  From pasture grasses for animal consumption to food crops, such as oat and barley, for human consumption, grasses make up the world’s most significant food source.

Around the world, there are 11,400 known grasses. Incredible? The Royal Botanic Gardens at Kew painstakingly compiled the list of all grass species that we know about. It shows the huge potential for exploring new species to use in lawn seed mixtures. Whilst there is this vast list of plants in the Poaceae family, different types of grasses have some similarities. All grasses produce seeds that are monocotyledonous, which means that each seed produces only one leaf sprout. Additionally, most grasses are herbaceous, so they don’t produce woody stems, and they die back to the ground at the end of the growing season.

A Valuable Resource

Grasses are invaluable assets to our planet and its inhabitants. With a better understanding and appreciation for grasses, you may never look at your lawn the same way again.
