Amazing grass

Grass has an ability to grow after it is cut that far exceeds the regenerative abilities of most other plants. Unlike an oak tree, which dies if you cut it off half-way up its trunk, grass can continue to grow after it has been sliced in two. Trees grow from the tips of their branches; grass grows from the bottom of its leaves--thus if you cut the top part of a grass stem or leaves off with a lawn mower, the plant will easily send out new leaves to grow from the bottom. This makes it ideal and able to survive lawn care, not to mention cattle grazing.

Also an ordinary lawn is made up of thousands of different grass plants, some connected to each other by rhizomes (below ground), others by stolons (these are above ground. Some experts say that a 1,000 square feet of lawn might have one million grass plants.
