Green stuff growing in my yard

There is green stuff growing in my yard. I do not remember seeing it yesterday, I suspect it grew over night. That sounds like the beginning of a science fiction story; I realize the plants were probably there yesterday and I did not notice them.

Las Vegas received a great deal of rain in the past couple of months, therefore, I should expect green plants in my front yard. Now the plants, or perhaps I should write weeds, are pretty, but this will not last long. As soon as the rain stops or summer comes, the plant will die and turn brownish gray and ugly. At that time, I must have them removed.
