When they planted wildflowers along the motorway at Bombay I thought it was the prettiest sight. It made driving that stretch of road so enjoyable. The flowers have long since gone, but my memory of them still remains.
Autumn is perfect planting time for wildflower seeds. You can get this bee friendly (always good!) mix right here, and the price is really good. I want to buy a mix & sprinkle them in random places.
