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.
(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.
('Blue Seniorita' Mexican Sage) Smallish rich cobalt blue flowers come in large clusters on this unusually strong growing shrub. From late summer through fall you and the hummingbirds will be delighted with this rare variety.
(Huntington Garden Mexican Sage) In areas with mild end-of-year weather, this sage is a tower of nectar for hummingbirds. Large blue-to-purple flowers shaped like open parrot beaks reach out from dark calyxes. Their spikes stretch out horizontally and gently curve upward from the plant's mid-green foliage.
(Variegated Mexican Sage) Although its deep violet flowers are compelling, it is the foliage of this sage that is its greatest attraction. Kelsi is full of surprises, including asymmetrical leaves that make this variety easy to identify.
(La Placita Mexican Sage) Large and deep violet, the flowers of this tidy shrub bloom from late summer through fall. La Placita (the public square or small plaza) was collected in the mountains of Hidalgo, Mexico.
(Lolly's Mexican Sage) Our variety of Salvia mexicana 'Lolly' is the tall kind growing up to about shoulder height. A shorter form is often called "Lollie Jackson" or "Lolly Jackson." Who or what the mysterious Lolly is remains unclear.
(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.
(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.
(Blau Hügel Meadow Sage) When in bloom, petite Salvia nemorosa 'Blue Hill' more than doubles in height. Its tall, spike-like racemes of violet-blue flowers are so dense and compact that this woodland sage is sometimes called "Blue Mound."
(Burgundy Candles Meadow Sage) When the burgundy buds of Salvia nemorosa 'Burgundy Candles' open, deep violet-blue flowers emerge. They are supported by burgundy and green bracts on purple stems.
(Lyrical Silvertone Meadow Sage) European Meadow Sages are known for their intense color. However, Salvia nemorosa 'Lyrical Silvertone' is exceptional for its violet-blue and silver two-tone flowers supported by dark calyxes.
(Nodding Sage) "Dancing in the air" is how garden writer Joseph Tychonievich describes the tall, graceful flower spikes of Nodding Sage, which can tower up to 5 feet tall over the plant's 18-inch-tall foliage during the summer flowering season.
(Giant Purple Desert Sage) It’s best to plant this flamboyant native of the Southwest in spring or summer. However, once established, it tolerates winters from USDA Zones 5 to 9. Purple tubular flowers and burgundy bracts flare up its 10-inch flower spikes like flames on this softly rounded shrub.
(Pale Sage) Powder blue flowers are cupped by lavender calyxes on this lovely yet little-used sage native to moist meadows in Argentina. It is a tall, narrow plant with delightful oval-shaped leaves with scalloped margins.
(Blue Angel Gentian Sage) Since the 1838 discovery of this herbaceous species from Central Mexico, Salvia patens has been a mainstay of the perennial garden. Blue Angel is one of the smallest of the full-sized varieties.
(Cambridge Blue Gentian Sage) Cambridge Blue is one of the most famous varieties of Salvia patens, which was discovered in Central Mexico in 1838. Its powder blue flowers are delightful and cooling in the landscape.
(Giant Gentian Sage) What makes Salvia patens 'De Flores Gigantes' truly giant is the size of its true blue flowers. However, this variety from Argentina is tall as well.
