Black and blue salvia is a perennial that produces blue flowers from late spring to early fall. The stems and leaves are dark to sage green in color, and the brilliant blue flowers have black sepals just below the petals. This plant is a favorite for growing in pots, borders or hedges. Salvia is a clumping plant that can be divided in the spring or fall every five to six years. You can also start it from seed and transplant the seedlings when the weather is warm enough.

Instructions
- Take potted plants to a sheltered location outdoors and leave them there several hours each day for one week, after all danger of frost has passed for your area. This helps harden off seedlings and lets them become accustomed to the outdoor environment.
- Select a garden planting location that gets full sun or partial shade.
- Dig a hole as wide and deep as the pot your salvia is currently growing in. According to Burpee.com, black and blue salvia tolerates many types of soil, but well-drained soil that’s rich in nutrients will provide the best results.
- Water the potted salvia, then gently loosen the roots from the pot and turn it over into your hand.
- Place the roots and soil into the hole you dug, and back fill with the extra soil. Tamp down gently to ensure good root contact and remove air pockets.
- Water the new transplants gently, giving them enough to moisten the soil without saturating it.
