Black & Blue salvia delivers spiky dark purple flowers over deep green foliage all season long, thriving in the heat without complaint. It spreads steadily to fill a bed or border, never needing staking or fussing.

Plant in a sunny spot with decent drainage and let it go. Water in during dry stretches, pinch it back once or twice in early summer to thicken it up, and it will keep flowering from planting time straight through fall.
