Q: Any idea where I might purchase some ‘Golden Archangels’ lamium? I saw some at the East Cobb Master Gardener’s tour of homes and it was absolutely beautiful.

A: I try to look for the positive in any pest plant. Poison ivy has attractive fall color. Kudzu provides food and shelter for animals. Yellow archangel, Lamiastrum galeobdolon, has attractive green and white foliage and it certainly makes a quick growing groundcover. But I advise extreme vigilance after installing this plant. I have had numerous ferns, hosta and heuchera fall victim to its advances. I planted some in 1995, began killing it in 1998, and it still pops up unwanted in my woodland garden.
