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.
(Ocampo Mexican Sage) Growing from 7 to 10 feet tall each year, this is the largest of our Mexican Sages. Yet due to its erect form, this sage only spreads 36 inches. It has large, deep violet flowers with almost black calyxes that rise up on tall spikes and dark green, heavily veined foliage.
(Door of the Fox Mexican Sage) Purplish foliage contrasts attractively with the violet-to-purple flowers of this big sage, which grows 6 feet tall and 4 feet wide. Bloom time is autumn. This darkly dramatic Mexican Sage makes a particularly attractive entryway accent.
(Russell's Mexican Sage) Expect rapid, tall growth from this Salvia Mexicana . In the ground, Russell’s Mexican Sage can reach up to 10 feet tall and 5 feet wide, providing an effective screen of dark green, heart-shaped foliage. By late autumn it’s bursting with flowers.
(Little Mexican Sage) This low-growing sage is a shrub in its warmest zones and a perennial in the cooler ones. It's just right for small spaces or tiny gardens. Short and compact, its flowers are similar to but smaller than those of S. mexicana 'Limelight'.
(Byron's Mexican Sage) One of our favorite Mexican Sages, this large variety is reputed to be a hybrid between Salvia mexicana and S. hispanica -- a species of Chia Sage.
(Blast Pink Mountain Sage) Long blooming Salvia microphylla 'Heatwave Blast' produces prolific quantities of large, dusky salmon-pink blossoms and dense, mid-green foliage.
(Heatwave Red Mountain Sage) Compact and small, this Mountain Sage is another fine groundcover for Southern California, the Southwest and Texas. Similar to Salvia microphylla 'Heatwave Glimmer', it not only survives but thrives in extreme heat.
(Brilliance Pink Mountain Sage) Long blooming Salvia microphylla 'Heatwave Brilliance' produces prolific quantities of deep reddish-pink, or cerise, blossoms along with dense, mid-green foliage.
(Glimmering White Mountain Sage) Heatwave Glimmer isn't a mirage. It is a Salvia microphylla that tolerates extremely hot climates as well as cooler regions. It doesn't just survive; it thrives in the heat of Southern California, the Southwest and Texas.
(Glittering Pink Mountain Sage) Mountain Sage (Salvia microphylla) handles hot climates as well as cooler coastal regions. It withstands the high temperatures of Southern California, the Southwest and Texas.
(Glow Peach Mountain Sage) Long blooming Salvia microphylla 'Heatwave Glow' produces prolific quantities of soft peach-to-apricot blossoms along with dense, mid-green foliage.
(Radiance Bright Pink Mountain Sage) Long blooming Salvia microphylla 'Heatwave Radiance' produces prolific quantities of hot pink blossoms along with dense, mid-green foliage.
(Scorching Pink Mountain Sage) Compact and small, this Mountain Sage is another fine groundcover for Southern California, the Southwest and Texas. Similar to Salvia microphylla 'Heatwave Glimmer', it not only survives but thrives in extreme heat.
(Sparkle Pink Mountain Sage) Long blooming Salvia microphylla 'Heatwave Sparkle' produces prolific quantities of deep mauve-pink blossoms with white throats and dense, mid-green foliage.
(Hot Lips Sage) What a winner for fascinating flowers! Salvia microphylla ‘Hot Lips’ is a native of Mexico that produces a combination of solid red, solid white, and bicolor red and white blossoms all on the same plant and sometimes at the same time.
(Killer Cranberry Mountain Sage) Masses of magenta flowers on tall spikes lure honeybees and hummingbirds to the rich nectar of Salvia microphylla 'Killer Cranberry'. Its prolific flowers are a killer attraction for people too.
(Trinity Mountain Sage) Heat and drought tolerant, this Salvia microphylla is native to Northeastern Mexico where summers are dry and temperatures can rise to more than 100 degrees F. It can survive winter temperatures down to 0 degrees.
(Azure Hybrid Sage) Despite its name, the flowers of this tiny hybrid aren't really blue. They are a light purple. Due to its size, long bloom time, heat tolerance and drought resistance, Salvia x 'Mesa Azure' is a fine groundcover for areas where summers are hot and dry.
(Big Orange Mountain Sage) When temperatures are cooler in spring and fall, the persimmon-orange flowers of this large Mountain Sage darken. Gray-green foliage, bright green calyxes and reddish-green stems add to the plant's fascinating look, which mixes well with yellows and blues.
(People's Park Mountain Sage) Sometimes nature can be rebellious. This is one the Mountain Sages known as the Turbulent Sixties Series developed from an outlaw cultivar of the Southwestern native Salvia microphylla. Monterey Bay Nursery (MBN) named their accidental hybrid ‘Berzerkeley.’
(Red Velvet Mountain Sage) This is one of the most intense red-flowering variety of Mountain Sage we grow. Medium-sized flowers are profuse on this large, vigorous plant -- particularly in spring and fall. Dark stems and calyxes intensify the plant's drama along with glossy green foliage.
(Rosie O'Grady Mountain Sage) Honeybees and hummingbirds love the large, bright pink flowers of Salvia microphylla 'Rosie O'Grady', a drought-resistant sage. Dense and fragrant, it's large, glossy green leaves are veined and have finely serrated edges. This is a lush choice for dry gardens.
(Royal Bumble Mountain Sage) Almost black, the stems and calyxes of this UK hybrid form a pleasing contrast with its medium-size scarlet flowers and glossy green leaves. Bloom time is spring to fall. This Mountain Sage suckers freely and forms a dense clump.
(St. Charles Day Mountain Sage) Especially in spring and fall, masses of red-violet flowers bloom amid the silvery green foliage of Salvia microphylla 'San Carlos Festival'. Put this one into the "must have" column.
(Telegraph Avenue Dwarf Mountain Sage) Here’s another member of the Turbulent Sixties Series of Southwestern Mountain Sages (Salvia microphylla), which developed from one of nature’s rebels – an accidental hybrid that Monterey Bay Nursery (MBN) named ‘Berzerkeley’ after finding it taking a stand in the nursery’s gravel paving.
