If you live some place with a winter, you will have a barren patch of dirt then. If you live somewhere with a long, cold, wet fall or early spring, then you hill have a tiny field of mud for the local animals to wallow in.

If you live within throwing distance of a neighbor who does not wish to have a lawn of dandelions, you will be a target of ill feelings for your invasive weed colony.

Lawn grasses have been selected to keep the ground covered and tolerate being walked on and played on. If you don't want to walk on or play on your yard, then there is a wide choice of ground cover that keeps the ground covered all year long and isn't a wildly airborne spreading invasive weed.
