Borago officinalis

Borage has naturalized nicely into our garden. It has many uses both medicinal and culinary, but it's so pretty and always welcome around here.
Tomorrow is the neighborhood plant exchange; I'll look for little starts of the borage to pot up and bring to that.
I'm looking for a quick cure for the powdery mildew that has attacked the ninebark tree. We've apparently had the perfect conditions for this fungus: high humidity and dry leaves.
