Hardiness Zone: (annual)
Other Names: Munz's Sage
A beautiful, aromatic sage bearing clusters of light blue flowers, in dense whorls above the foliage; a compact, dense plant that tolerates summer water and heavier soils; a dependable choice in the garden
San Diego Sage has masses of beautiful spikes of sky blue tubular flowers with white throats rising above the foliage from mid spring to late summer, which are most effective when planted in groupings. The flowers are excellent for cutting. Its fragrant narrow leaves remain green in colour throughout the season. The fruit is not ornamentally significant. The tan stems can be quite attractive.
San Diego Sage is a multi-stemmed annual with an upright spreading habit of growth. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.
This plant will require occasional maintenance and upkeep, and should be cut back in late fall in preparation for winter. It is a good choice for attracting 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.
San Diego Sage is recommended for the following landscape applications;
- Mass Planting
- Border Edging
- General Garden Use
- Container Planting
Planting & Growing
San Diego Sage will grow to be about 5 feet tall at maturity, with a spread of 5 feet. Although it's not a true annual, this fast-growing 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 prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This species is native to parts of North America. It can be propagated by cuttings.
San Diego 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. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
