A few years ago, I bought a packet of wildflower seeds and spread it in a small sunny garden patch right next to the sidewalk. Who knew that coneflowers, daisies, and black-eyed susans, etc. will come back year after year? My husband thought they were too tall, wild, and out of control. So I tried to get rid of them. A word of advice. Be careful with wildflowers. They are HARD to get rid of.
I kind of like the cottage-garden look of my "warm-palette" wildflower patch. It doesn't look as pretty as the painting now, with lots of spent flower heads that need to be trimmed. But who has the time!
