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.
(Himalayan Sage or Kashmir Sage) The word "hians" in Salvia hians means "gaping" and refers to the hanging lip of this sage's flowers, which bloom from late spring through early fall. This may or may not the "true" species as it is described, hence the term aff or affnis in the name, which indicates that this plant is related to, has an affinity to, but is not identical to Salvia hians.
(Blue African Sage or Blousalie) A handsome, densely branched shrub with small, gray leaves, this Salvia puts on a show when in full bloom. The pale blue flowers bloom on foot-long spikes that cover the plant. Each flower has a large, trumpet-shaped, green-and-red bract at its base.
(Amethyst Sage) Growing up to 12 inches long, the triangular basal leaves of Salvia amethystina subsp. ampelophylla are the largest we know among sages. They have long silky hairs on their undersides and are fragrant when bruised.
(Stem Clasping Violet Sage) Like a candelabra lit up with whorls of violet blossoms, the erect, branching flower spikes of Salvia amplexicaulis make this native of Southeastern Europe shine. On the Grecian island of Thassos, it brightens areas near the beach.
(Arizona Deep Blue Sage) In contrast to the lavender-blue flowers of Arizona Blue Sage (Salvia arizonica), the blossoms of Arizona Deep Blue are nearly purple. They are the kind of deep lavender that you might see in a southwestern sunset.
(Iranian Oil Sage) Butterflies and honeybees are drawn to the long blooming, dusky violet-blue flowers of Salvia atropatana. However, deer say no to its charms, due to its essential oils being less than tasty.
(Prairie Sage) Native to a large part of the central United States, this perennial Salvia is a beloved wildflower, delighting us with large cerulean blue flowers. Hummingbirds and butterflies love it as well.
(Rhythm and Blues Anise-Scented Sage) The large, deep bluish-purple flowers of Salvia BODACIOUS ‘Rhythm and Blues’ are shaped like parrot beaks and supported by black calyxes. It's foliage smells sweet with a hint of licorice. It's superior to the old standby Salvia guaranitica 'Black and Blue'.
(Pacific Blue Sage) Whorls of deep lavender-blue flowers contrast brightly against the dark maroon stems of this likely hybrid of Salvia brandegeei and Salvia munzii.
(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.
(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.
(COOL Periwinkle Anise-Scented Sage) Dusky green bracts cup the lavender-blue blossoms of Salvia COOL Periwinkle that attract hummingbirds. The fragrance of its bright green leaves may remind you of licorice.
(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.
(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.
(Red Veined Sage) In 1827, John Wilkes referred to Salvia haematodes as "Bloody Sage" in his Encyclopaedia Londinensis, Volume 22. This might seem mysterious when first viewing the sage's upright yet somewhat relaxed spikes of whorled, violet-colored flowers.
(Atlas Mountain Sage) Tawny looking from a distance, the Atlas Mountains of northern Africa are home to an abundance of greenery, including the lovely Salvia interrupta. So the mountains contrast sharply with the Sahara Desert, which they border.
(Japanese Woodland Sage or Shu Wei Cao) This short, lavender-flowered, ornamental sage has purple-to-green foliage. In Asia, this woodland plant has long been an important medicinal herb, used in the treatment of conditions such as diabetes.
