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. |
(Blue Turkish Sage) Large velvety gray-green to white leaves in loose rosettes give this sage a distinctive look as does the celestial violet-blue of its flowers. The blossoms seem much too large for this short sage and its thin, candelabra-branched flower spikes.
(Vermilion Bluffs® Mexican Sage) The brilliant red flowers of Vermilion Bluffs bloom abundantly from August to October. This variety of the Mexican native Salvia darcyi is cold hardy to Zone 5b at altitudes up to 5,500 feet.
(Pilgram's Rest Pink Sage) Spring into summer, this heat-tolerant sage from South Africa produces lilac and white blossoms with profuse, fragrant, gray foliage. It's the burgundy calyxes, which turn a rusty pink after the flowers blossom, that give this sage part of its common name.
(Blue Ecuadorian Sage) A densely branched shrub with silvery leaves and dusky blue flowers, this rare species was once thought to be Salvia cruickshanksii. In the nursery trade, it sometimes is called Salvia 'Equador'.
(Greek Sage) Most of the dried culinary sage sold in the United States is Greek Sage. Frescoes on the island of Crete dated to 1400 BC depict this plant, which was used by the Phoenicians and Greeks for cooking and medicine. It is an ancient and beloved friend of mankind.
(Elk Pomegranate Autumn Sage) We're proud to say that this is an FBTS cultivar. It is one of the finest dark flowered, compact Autumn Sage varieties we have seen. Its extraordinarily large, raspberry blossoms bloom from spring into fall.
(Furman's Red Autumn Sage) Selected by noted Texas plantsman W.A. Furman in the 1970s, this hardy Texas native is beautiful and tough withstanding heat, drought and freezing winters. Its flowers, which bloom spring through fall, are a rich, saturated red bordering on magenta.
(Grace Pink Autumn Sage) Dark hot pink flowers and contrasting, dark bracts make this Autumn Sage stand out. Originally fom the JC Raulston Arboretum in North Carolina. This variety is large but compact, rugged, heat tolerant and capable of handling Zone 6 chill.
(Lipstick Autumn Sage) Similar to a little bit of lipstick on a pretty face, the rosy flowers of this hardy, heat-tolerant sage add a finishing touch to a perennial Salvia border. The creamy pinkish-red blossoms have a contrasting white throat and are cupped by rosy brown calexes on long spikes.
(Navajo Autumn Sage) Even a hint of blue is unusual among Autumn Sage flowers. Salvia greggii 'Navajo Purple' is a rarity due to its magenta-purple blossoms, which hint at natural hybridization including a mystery parent in the blue range, such as Salvia lycioides.
(Big Orange Autumn Sage) Standout color is the big draw for this large growing Autumn Sage. Collected in the mountains of Northern Mexico, it grows well in a wide range of climates, including the hot dry Southwest and the cool moist Pacific Northwest. A difficult color to capture in a photo, it is well described as a warm orange with a scarlet overlay.
(Pink Preference Autumn Sage) Two-tone, hot pink flowers and contrasting, nearly black bracts make this Autumn Sage stand out. This drought tolerant Autumn Sage from Central Texas is also compact, rugged, heat tolerant and capable of handling Zone 6 chill.
(Pink Beach Autumn Sage) When it blooms from spring into fall, this heat- and chill-tolerant sage is covered with large, two-tone pink flowers that attract butterflies, honeybees and hummingbirds. This compact, drought-tolerant beauty also features small, shiny, bright green leaves.
(Radio Red Autumn Sage) Dark calyxes support true red blossoms in Salvia greggii 'Radio Red', a 2015 introduction from the Darwin Perennials division of Ball Seed. Its tiny, smooth, elliptical leaves form a light, airy backdrop for the dramatic flowers.
(Salmon Autumn Sage) Creamy salmon-colored flowers with white throats make this elegant Autumn Sage perfect for a pastel garden or as a cooling color in a mixed sage border. Bloom time is spring into fall for this petite Salvia greggii native to the American Southwest and Mexico.
(Stormy Pink Autumn Sage) The dramatic name of this floriferous Autumn Sage is due to the calyxes cupping its smoky apricot-pink blossoms. Some gardeners report gray calyxes and others say dark plum. But for whatever reason, the Stormy Pink that we grow on our Northern California coastal farm has green calyxes with dark stripes.
(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.
