Our driveway is absolutely covered with these tiny white flowers. At first I thought they were specks of vinyl dust from cutting pieces for the siding, but they are actually flowers. Millions of flowers. That is my shoe in the picture to give some scale. My camera does not do close-ups.
I dumped this sand from my saltwater aquarium on the driveway. This weekend hundreds of bees of several different sorts found it. There were a lot of honeybees and several smaller kinds.
I will be shoveling the sand up and putting it in the garden area where they can get at it without being run over by a car.
