Mexico is a land of almost unimaginable plant diversity, including the highest concentration of native sages (Salvia spp.) in the world. It is home to nearly a third of the approximately 900 Salvia species worldwide.
The rich biodiversity of Mexico is due, in part, to its many types of climates from the deserts of Northern Mexico and Baja to the mountainous cloud forests at its southern boundary with Guatemala.
Salvia is a member of the mint family (Lamiaceae). Although Lamiaceae is only the eighth largest plant family in Mexico, Salvia is one of the country's largest genuses. It is a genus with species fit for many climates, which is exactly what Mexico has. Consequently, Mexican sages grow beautifully in many parts of America. Some are even cold hardy to USDA Zone 5.
One factor that causes Mexico's climate to vary so much despite its closeness to the equator is the country's up-and-down geography; it is a land of many mountains and numerous changes in elevation. Some peaks -- such as the volcano Pico de Orizaba near the port of Veracruz in southeastern Mexico -- are topped with snow and glaciers year round even when their lower slopes are hot in summer.
Mexican native species range from drought-tolerant sages that grow best if given little water and lots of sunlight to ones that can take heat, but prefer partial shade and plentiful moisture. They tend to be long-blooming plants with a rainbow of flower colors.
Many Mexican sages are fragrant. On warm summer days, they lend a heady perfume to the landscape when planted near home entryways or as borders along walkways. They include low-growing groundcovers as well as plants so tall, wide and floriferous that a group planting forms a dramatic privacy screen.
Some of these plants are the source of age-old folk remedies and the focus of current medical research; their potential health benefits are modern day treasure. And here is one more thing that is golden about Mexican native sages: these lovely additions to home gardens require little fuss.
(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.
(Winter Mexican Sage) Call it the Snow Queen! From fall through spring, this graceful, colorful sage blooms through 20 degree F weather despite snow and ice. It has lovely, small, dark green leaves and profuse clusters of tubular, cinnabar-red flowers that puff out in the center.
(Roseleaf Sage) A late but glorious bloomer, Roseleaf Sage starts producing hot pink blossoms in winter and continues into spring -- growing more spectacular every day -- unless cut down to the ground by hard frost.
(Hidalgo Roseleaf Sage) The earliest flowering, hardiest and strongest growing cultivar of its species, Hidalgo Roseleaf Sage starts blooming in June on the Northern California coast. It continues, and becomes more spectacular every day, until cut down by hard frost. In our mild climate, it never stops blooming some years.
(Scandent Mexican Sage) Here's another winter-blooming hummingbird magnet for gardens in mild climates. This one is scandent, which means it is a climber and needs support. Its abundant, purple-to-magenta flowers are velvety and 6 inches long.
(Violet Calyx Sage) Here's another abundantly blooming sage from the cloud forest slopes of Chiapas, Mexico. Violet beelines mark the lower lip of the crimson blossoms, which are so numerous that it can be difficult to see the foliage at times.
(Karwinski's Sage) From moist mountain areas in Mexico and Central America, this rugged, winter-blooming shrub is found in oak or pine forests at altitudes of 4,000 to 8,000 feet. This may account for this winter bloomer's ability to produce some bright, brick-red flowers even during short periods of freezing weather with temperatures as low as 20 degrees F.
(Giant Karwinski's Sage) San Francisco arborist and gardener extraordinaire Ted Kipping developed this tower of creamy pinkalicious power that hummingbirds love. It's lush with bright green leaves that are large, pebbly and hairy on the underside.
(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.
(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.
(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.
(Variegated Mexican Bush Sage) Although slow growing and somewhat finicky, this sage is a must-have for lovers of unique foliage. It has small purple flowers and highly variegated leaves with stems that are slightly twisted. The overall look is compact and dense.
(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.
(Oaxaca Orange Wooly Sage) Tall, eye-catching spikes of dusky red-orange flowers that bloom from summer into fall make this one of our most impressive Salvias. Plus it's cold hardy into Zone 7.
(Forysthia Sage) This statuesque perennial grows up to 10 feet tall, but spreads only 3 feet wide. It is a late bloomer from Mexico's Sierra Madre Oriental mountains where it grows at altitudes of 4,000 to 5,000 feet and tolerates temperatures down to 20 degrees F.
(Red Stem Forsythia Sage) The thick, square, red stems of this variety of Forsythia Sage make it conspicuously different from the species and from everything else in your garden. Its jointed stalks look a little like rhubarb gone mad!
(Silver Leaf Forysthia Sage) It's the foliage of this clone that makes it so different from its parent plant. The leaves are a lovely silver and smaller than the green leaves of the species. However, they both have buttery yellow, Forsythia-like blossoms.
(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.
