Volunteer with Pretty Flowers

When Hurricane Ike & an accompanying tornado blew through town, it toppled my neighbor's fence which came crashing down on an old bird bath, the remnants you see in this photo. Over the past two and a half years, the old bird bath has developed enough soil to entice a pretty weed to grow there. The plant has lovely purple flowers and long, slender green leaves. A friend of mine has a whole grouping of them in her front yard and when asked, she cannot name the plant. So, it remains a "weed."
