I planted this field a year ago 13 months ago. I wanted to mow it in the fall, but it was way too wet. I finally got a chance to mow at the beginning of May, and the flowers are doing great. I have a slight weed and grass problem, but I believe I'll be in good shape as the flowers mature. This is a regional (northeast) mix from the Vermont Wildflower Farm. This pic doesn't do them justice as there are a lot more blooming now.
