Blue flowers, especially true primary blues, are highly valued in most gardens due to being rare. The genus Salvia includes some of the clearest and truest of blue blossoms. In his book, The Science of Plant Colors, Dr. David W. Lee notes that there is no true blue pigment in plants. According to Dr. Lee, biology professor emeritus at Florida International University, "Less than 10 percent of the 280,000 species of flowering plants produce blue flowers." Blues are derived from red pigments called anthocyanins that plants modify through shifts in their chemistry.
The Salvia genus contains some of the truest and clearest of blues. We grow only the best of the best.
(Cedros Island Sage) From the Island of Cedars off the coast of Baja California Sur comes this delightful xeric sage with deep violet-blue flowers and silvery foliage. The square-shaped, 1-inch-long leaves are densely covered with downy, short, white hairs providing moisture retention.
(Silver Germander Sage) With its compact habit, brilliant silver-white leaves and large, sky blue flowers, this is an outstanding heat-tolerant choice for dry, sunny gardens. We consider this to be one of the finest short ground covers for these conditions.
(Marine Blue Sage) The name and origin of this fine cultivar has long been in dispute. It may be a clone or hybrid of the Mexican plant Salvia chamaedryoides var.isochroma. It is one of the prettiest, strongest sages we grow.
(Rough Blue Sage) Honeybees and butterflies love this deer-resistant shrub, which grows wild on the southwestern Cape of South Africa. It is a member of the most diverse plant community in the world, the fynbos -- an Afrikaans word, meaning "fine bush" and referring to scrub plants or shrubbery.
(Chinese Sage) Although this is a perennial species, most people in the U.S. who are familiar with Chinese Sage, probably know the annual variety Salvia chinensis . The perennial form is reliable; we’ve grown it for several years. However, little has been written about it.
(Snowflake Sage) Wiry, trailing stems of small white leaves make this plant look like fresh snowfall. Numerous, small, sky blue flowers with prominent bee lines further add to the cooling look. This dry-garden plant is native to the mountains of the Chihuahuan desert of North Central Mexico.
(Golden Leaf Sage) A tinge of gold in its fuzzy, pebbled foliage gives Salvia chrysophylla its common name. Abundant lavender flowers with pale cream lower lips make it stand out in the landscape.
(Cleveland Sage or California Blue Sage) A California native plant garden is not complete without a Cleveland Sage. This particular cultivar has deeper blue flowers with a purple overlay as well as deep purple calyxes. Due to its height and drought resistance, it is ideal for back of border in a dry garden or for use as a screen.
(Michoacan Blue Sage) This unusual and distinctive Mexican sage grows from tuberous roots. It is compact and decidedly vertical with strong, square, winged stems that rocket upward and are topped with clusters of rich blue flowers in large rosy bracts come autumn.
(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.
(Elk Blue Hard Leaf Sage) Soft baby blue & white flowers in abundance coupled with strong growth make this an ideal new variety for hummingbird gardeners. the specific epitaph, durifolia, means hard leaf. We don't find the leaf exactly hard but it is lovely and durable.
(Silly Mexican Sage) Also known as Salvia roscida, this close relative of Blue Sky Mexican Sage (Salvia caudata 'El Cielo Blue') has thousands of deep violet-blue flowers with prominent white bee lines.
(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'.
(Balkan Sage) Violet-blue whorls of flowers and plentiful, fuzzy, basal leaves that reach an impressive length of 18 inches are two notable features about this hardy, herbaceous perennial, which is native to the Southeastern Balkan Peninsula.
(Ground Ivy Sage) Native to Central Mexico's highlands, this creeping perennial grows at a altitudes of more than 10,000 feet and can handle some chill. Its common name comes from its scalloped yellow-green leaves, which resemble Ground Ivy or Glechoma.
(Black & Blue Anise-Scented Sage) Hummingbirds go crazy for this variety of Salvia guaranitica. The black calyxes contrast handsomely with the rich, royal blue flowers. We highly recommend the much improved Salvia BODACIOUS 'Rhythm and Blues' as an alternative to this older variety.
(Elk Argentina Skies Anise-Scented Sage) Developed at FBTS, this new introduction is superior to the old standby, 'Argentina Skies'. Superior growth and earlier flowering make it a must-have choice for hummingbird gardeners.
(Sapphire Blue Anise-Scented Sage) The large, sapphire blue flowers of this Anise-Scented Sage glow in the full-sun or partial-shade garden from summer into fall. Similar to Salvia guaranitica 'Blue Ensign', this is a somewhat taller variety of the water-loving species.
