Other Names:  African Sage, Salvia namaensis x repens

Description:

An excellent variety presenting large sky-blue flowers, held over fragrant, attractively cut green foliage; tough and adaptable, great for dry garden conditions; excellent plant for summer containers

Ornamental Features

Savannah Blue Sage has masses of beautiful spikes of sky blue flowers with brick red calyces rising above the foliage from early to late summer, which emerge from distinctive purple flower buds, and which are most effective when planted in groupings. The flowers are excellent for cutting. Its attractive deeply cut ferny leaves remain green in colour throughout the season.

Landscape Attributes

Savannah Blue Sage is an herbaceous annual with an upright spreading habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. It is a good choice for attracting bees, butterflies and hummingbirds to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Savannah Blue Sage is recommended for the following landscape applications;

• Mass Planting
• Border Edging
• General Garden Use
• Groundcover
• Container Planting

Planting & Growing

Savannah Blue Sage will grow to be about 24 inches tall at maturity extending to 3 feet tall with the flowers, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 18 inches apart. Although it's not a true annual, this plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.

This plant does best in full sun to partial shade. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. This plant does not require much in the way of fertilizing once established. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Savannah Blue Sage is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
