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.
(Van Remsen's Anise-Scented Sage) Big and beautiful, this Anise-Scented Sage grows up to 7 feet tall in rich soil and has lavender-to-purple flowers. In our garden, it blossoms from late spring to fall, attracting both honeybees and hummingbirds.
(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.
(Turkish Mountain Sage) Part of the Salvia canescens group of Mediterranean sages, this dwarf species features lavender parrot-type flowers with whitish lower lips (or should we say beaks!).
(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.
(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.
(Purple Leaf Tall Big Leaf Sage) Bright green on top, the long leaves of this distinctive sage are a dark, furry purple on the undersides. Like the more typical green form of Salvia macrophylla, this variety has cobalt blue flowers that seem to float in airy clusters on 12-inch-tall branching spikes.
(Creeping Big Leaf Sage) Cobalt blue flowers float in airy clusters above the giant, velvety, green leaves of this South American native. Short and spreading by woody rhizomes, this is an ideal groundcover. As a bold statement in a container, it has no equal.
(Tall Big Leaf Sage) Cobalt blue flowers seem to float in airy clusters on 12-inch-tall branching spikes above the bright green, velvety foliage of this South American native. Up to 5-feet tall, tidy and upright in habit, this sage makes a fine background or border planting when massed.
(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.
(Black Sage or Honey Sage) One of the most common and fragrant native shrubs in Central California's Coast Ranges, Black Sage is ideal for dry gardens. Admirably adaptable, it tolerates soils ranging from the most marginal to ones that are loamy and provide excellent drainage. It is a survivor.
(Dry Earth Black Sage) Black Sage Salvia mellifera is one of the most common and fragrant native shrubs in the California Coast Ranges and is ideal for dry gardens. At 12 inches tall by 5 feet wide, this variety is an excellent groundcover.
(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.
(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.
(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.
(Red Sage, Chinese Sage, Dan-shen) The bright red, finger-like roots of Salvia miltiorrhiza have a long history in traditional Chinese herbal medicine.
(Elk Blue Little Sage) if it were up to us, we would never have named this plant Little Sage. Although it is dainty, it is also one of the most fascinating species we grow. We particularly love its pebbly, oval leaves that are a shiny purple/green on top and a furry white below.
