Robusta is a select form of Salvia dorrii v. incana chosen for its large size, attractive foliage and a massive display of sky-blue flowers in late spring. Easy to grow, the shrub has silver evergreen foliage and is easily grown in any well-drained soil.
Variety incana, originally collected from the Cascade Mts. of Washington, is a distinct form of this wide spread western native shrub. After growing it alongside other forms of Salvia dorrii, chief horticulturist David Salman, found ssp. incana to be notable for its upright growth habit, large, pure silver leaves and sky-blue flowers held in silver calyxes. A late spring bloomer, the plant really stands out when planted with cacti and other green leafed xeric plants. Highly recommended for gardeners plagued by deer and other browsing animals.

Salvia (commonly referred to as ‘Sage’) represent a huge family of ornamental plants that attract a variety of pollinators to their nectar rich flowers. They are resistant to deer and rabbits.
Plant in full sun.
Plant native Western Salvia varieties in soil that is low fertility and well-drained.
Plant Old World Salvia in a wide range of soils (loams, sand) including clay.
Many spring-flowering varieties of sage will re-bloom in fall if deadheaded after the first bloom.
New transplants need regular irrigation their first growing season to establish themselves. Once established they will need regular, deep irrigation during hot, dry weather.
During fall garden clean-up, wait to cut back the plants until spring for improved cold hardiness.
In colder USDA zones (zone 6 and below) it is essential to give Native Southwestern and Southwestern hybrids protection from the extreme cold their first couple winters in the garden. Mound up pine needles or fallen autumn leaves over and around the base of the plant.
Western Native Salvia: : It is from the Western US that we find our most beautiful native salvia species. For attracting hummingbirds, there are no finer flowers than the Western native sages. Typically, this group of Salvia prefer ‘lean’ (not very fertile), well drained soils. They will grow in dry clay conditions in arid climates but will rot out in clay soils where there is more than about 15 to 18” of precipitation annually.
Western Salvia include:
Salvia greggii - ‘Furman’s Red’, ‘Cold Hardy Pink’
Salvia hybrids - ‘Maraschino’, ‘Raspberry Delight’, ‘Ultra Violet’ and ‘Burgundy Seduction’.
Salvia pachyphylla and Salvia dorrii is recommended for arid western gardens.
Salvia azurea and Salvia reptans - Early fall bloomers with excellent cold hardiness.
To get established in USDA zones 5 & 6, Western Salvia (noted above) must be planted in spring or early summer, not in the fall. Protect your new plants over their first winter or two in your garden. Cover each plant with a generous pile of clean straw or pine needles. This allows the plant's crown (junction of root and branches) to mature and obtain maximum cold hardiness.
Old Wolrd Salvia: The Old World Salvia include some of the very best, most durable, longest-lived perennials. These salvia are an excellent choice for gardeners across most of the United States. ‘Old World’ Sages bloom primarily in shades of blue, pink and white. They are well adapted to cold climates and a wide range of soils including clay. The European Salvia are incredibly attractive to honey bees, many of our native bees and bumble bees as well as butterflies.
Old World varieties include:
Salvia syslvestris'Lyrical Rose', 'May Night', 'Little Night', 'Caradonna' and 'Marcus'.
