 | Drought tolerance is characterized by a plant's ability to get by on less water. Yet native climate often defines the boundaries of this trait. The plants in this list all share the ability to grow in arid conditions when water is scarce. A plant that tolerates and perhaps thrives on less than 15 inches of annual rain may be overwhelmed by moisture in a state where drought lowers the annual average from 50 to 40 inches. But Flowers by the Sea also gladly provides information if you ask about Salvias and companion plants that are appropriate for drought in damper parts of the nation. One definition of drought is a below-average amount of rain and snow over an extended period, such as during more than one growing season. Yet drought is caused by more than a shortfall of local precipitation. Even if your areaâs seasonal average of moisture is at a historically normal level, the level in another region may not be. If waterways and dams connect the two regions -- such as in the American West -- low river levels can mean decreased water storage and drought for both areas. Furthermore, if your regionâs population is growing but its water supply isnât, that can also lead to drought due to insufficiency. This adds up to a web of trouble that can only be untangled through water conservation. One effective conservation measure is to design gardens with plants that are attractive yet need little water. These are called xeriscapes, waterwise landscapes and dry gardens. Drought tolerance is closely connected to the term "xeric," a Greek word for "dryâ and the root of xeriscape. Xeriscapic plants include species accustomed to arid climates or dry summer/wet winter growing conditions, such as along coastlines with Mediterranean climates. The Salvias and companion plants in this list share the ability to grow when water is scarce. They are attractive even while surviving minimal summer water. Many are native to arid regions or are from Mediterranean climates. Before ordering plants, please carefully consider your local growing conditions in order to select species that will be right for your climate and yard. We're happy to provide recommendations. |
(Texas Wedding White Autumn Sage) This is our best white-flowered Autumn Sage. It is compact, hardy and blooms abundantly. We love it as a contrast to the generally bright colors of its group. Texas Wedding seems to always be blooming, with massive displays in spring and fall.
(Crimson Sage) Abundant and long blooming, the bright pink to red tubular flowers of Salvia henryi attract hummingbirds and form a pretty contrast with fuzzy, silvery foliage. This is a long blooming sage that is made for gritty soils, such as sandy loam.
(Jerusalem Sage) This lovely herbaceous perennial is native to Cyprus, Israel, Jordan, Lebanon, Syria, and the West Bank. Its clear pink flowers change at times to a pink highlighted with violet lines and dots. Prominent glandular hairs on the buds, bracts and floral stems exude a fragrance that is delightful on a warm day.
(Judean Sage) Native to the mountains of Judea in Israel, this dark violet flowered, perennial sage is unique among the Palestinian Salvias - as a woodland native it grows well in partial shade. It is a tough, drought-resistant plant with deeply cut & hairy foliage which forms impressive mounds of color in the spring and early summer.
(Yugoslavian Cut Leaf Sage) This is a rare Baltic steppe plant that grows beautifully in sunny locations with little water and excellent drainage. It is endemic to a the Orlova Brdo region of the Former Yugoslav Republic of Macedonia.
(Big Grape Sage) This lavender-flowered native of Northern Mexico resembles Salvia melissodora (Grape Scented Sage), but is bigger and also has larger leaves and flowers. It's a great companion plant for its little brother, which shares the same cultural needs and affinity for Zones 8 to 10. Both bloom from summer into fall.
(Kellerman's Sage) Rare in the United States, this wooly leafed, upright shrub comes from Southern Mexico and Guatemala. Mid-size, powder-blue flowers bloom on its long, airy stems from summer through winter in mild climates. It's lovely in mixed, drought-resistant plantings.
(Wooly Arabian Sage) "Radiant" is the word that garden writer and Salvia specialist Betsy Clebsch uses to describe the halo of white hairs covering the foliage and calyxes of Salvia lanigera.
(Wooly Multicolor Sage) In Greek, "lasiantha" means "wooly flower." The flowers of Salvia lasiantha are surrounded by wooly bracts, but are even more notable for transforming from apricot-orange in the morning to reddish-purple later in the day.
(Pink Mexican Bush Sage) Although native to Mexico and Central America, this elegant variety of Salvia leucantha was hybridized in South Africa. It is compact, long blooming and profusely covered by soft pink flowers surrounded by velvety white bracts.
(Midnight Mexican Bush Sage) The typical Mexican Bush Sage has purple flowers surrounded by furry white bracts. This clone from the San Francisco Peninsula has deep purple flowers, calyxes and stems. It is a good groundcover due to a mounding habit, smaller size and generous amounts of flowers.
(Mexican Bush Sage or Velvet Sage) Large purple and white flowers bloom abundantly on this compact dwarf plant. If you love the rich colors and velvety foliage of Mexican Bush Sage but have limited space or need a container variety, this one is is for you.
(Santa Barbara Mexican Bush Sage) This compact Mexican Bush Sage was found in the Santa Barbara garden of Kathiann Brown. It is, without a doubt, the finest short Mexican Bush Sage -- hardy, tough and long blooming. Add drought tolerance and dark, rich purple flowers to its list of merits.
(White Mischief Mexican Bush Sage) Profuse white blossoms and true white velvety bracts make the flowers of this South African hybrid a lovely choice for a wedding. In our experience, many of the plants sold as White Mischief are not the real thing. This tough, compact, long blooming sage is.
(California Purple Sage or California Gray Sage) This California native is commonly known as Purple Sage for its flowers or Gray Sage for its silvery, velvety foliage. Due also to its hardiness, drought tolerance and ability to attract small wildlife, it is a joy in the dry garden.
(Spreading California Purple Sage or Spreading California Gray Sage) Songbirds love this California native as do honeybees and hummingbirds. This Salvia leucophylla clone was collected in 1982 by Dr. Dale Smith of University of California Santa Barbara (UCSB #82152) at Point Sal near Santa Barbara.
(Saint Isidro's Sage) This hardy, lavender-blue-flowered Salvia comes from Southern Texas and has the same breeding as the famous Ultra Violet Autumn Sage. Although it needs warmer winter temperatures and has smaller foliage, it also does well in stressful conditions, including drought.
(Grape Scented Sage) With the grape scent of its pale lavender blossoms and its long history of medicinal use, it is no surprise that this sage is so widely distributed.
(Dry Earth Black Sage) Black Sage Salvia mellifera is one of the most common and fragrant native shrubs in the California Coast Ranges and is ideal for dry gardens. At 12 inches tall by 5 feet wide, this variety is an excellent groundcover.
