Many of my plant pairings are accidents. This is one such case. The perrenial originally planted where the annual salvia now grows died. I was hurrying to get my patio garden "up to snuff" for my mother's 75th birthday since it was front and center in the party space. The blue and red decorations must have influenced my plant choice, although I was unaware of it. I chose blue annual salvia to fill the gaping hole. When I got home and planted it next to the blood grass, I knew I had another perfect pair. Never in my life have I been so coordinated with garden plants matching party decorations. Who knew!
Note: Japanese Blood Grass is considered invasive. I have a small clump that I don't allow to expand. If you own this plant, pull any thin green off-shoots.
