This bush is in North-central Virginia on a farm. Most of each year when I lived there it would block the view of our pastures, interfere with mowing, and just look like a green mass. Every year, toward the end of winter, I'd say I was going to cut it down because I didn't like it. Then every spring it would flower and buy itself another year - thus earning my name for it - The Redemption Bush.
Someone said Deutzia, but it doesn't look like the examples I've found in other posts. Can anyone ID it?
