I feed the birds, and they are not really tidy eaters, so seeds fly hither and yon. If it were up to my husband–the lawn taker-carer–as those seeds started to sprout they would be pulled or weed whacked; but I convinced him to let them grow this time. And look what I got! Since this yard has no trees and only some container gardens I managed to get in, this blast of yellow that attracts birds, butterflies, and bees is a welcome addition. I am loving the color!
