5-27 Yarrow, Johnny-jump-ups, Knawel, Bristly Locust

5-27 Yarrow, AKA Milfoil, dots fields and roadsides.

Johnny-jump-ups, AKA Heart's Ease, has escaped from cultivation to lawns and dry sandy banks.

Dry sandy soil and waste places are favored by knawel. Its low spreading habits and its tiny white rimmed flowers doom it to obscurity yet it is a a wildflower.

Bristly Locust, planted ornamentally or as erosion control persists and spreads vegetatively - by root suckers - although most are sterile. John
