Taxonomy of Blue Hill Salvia:
Even experts in plant taxonomy have a difficult time with 'Blue Hill' salvia plants. You'll encounter all of the following scientific names for plants similar to the one in the picture at right:
- Salvia x superba 'Blue Hill'
- Salvia x sylvestris 'Blue Hill'
- Salvia x sylvestris 'Blauhügel' (its name in Germany, where the plant began)
- Salvia nemorosa 'Blue Hill'
- Salvia nemerosa 'Blue Hill'
These perennials put out small, lavender-blue flowers on spikes and reach 18"-20" in height, with a spread a bit less than that. The flowers are a lighter shade of blue than those found on 'May Night' salvia and 'Caradonna' salvia.
Sun and Soil Requirements for Blue Hill Salvia:
Grow Blue Hill salvia flowers in a sunny area with a well-drained soil. This is a drought-tolerant perennial. But as with most plants, it will be necessary to pay attention to young specimens to make sure that they are sufficiently irrigated.
Planting Zones for Blue Hill Salvia:
Blue Hill salvia flowers are best grown in planting zones 4-8.
Care for Blue Hill Salvia:
If you deadhead Blue Hill salvia flowers (i.e., remove spent blooms), the plants will flower all summer long. These perennials tend to flop over at the sides; to support them for better display, consider encasing the plants in a peony ring.
Uses for Blue Hill Salvia:
Blue Hill salvia leaves are fragrant enough to warrant drying, so that you may include them in potpourris.
