Zone 6 Salvias are generally hardy to -10 degrees F. They are mainly herbaceous perennials with soft foliage that dies back to the ground for winter. Others are subshrubs -- semi-woody perennials.
(Navajo Autumn Sage) Even a hint of blue is unusual among Autumn Sage flowers. Salvia greggii 'Navajo Purple' is a rarity due to its magenta-purple blossoms, which hint at natural hybridization including a mystery parent in the blue range, such as Salvia lycioides.
(Radio Red Autumn Sage) Dark calyxes support true red blossoms in Salvia greggii 'Radio Red', a 2015 introduction from the Darwin Perennials division of Ball Seed. Its tiny, smooth, elliptical leaves form a light, airy backdrop for the dramatic flowers.
(Texas Wedding White Autumn Sage) This is our best white-flowered Autumn Sage. It is compact, hardy and blooms abundantly. We love it as a contrast to the generally bright colors of its group. Texas Wedding seems to always be blooming, with massive displays in spring and fall.
(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.
(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.
(Yugoslavian Cut Leaf Sage) This is a rare Baltic steppe plant that grows beautifully in sunny locations with little water and excellent drainage. It is endemic to a the Orlova Brdo region of the Former Yugoslav Republic of Macedonia.
(Saint Isidro's Sage) This hardy, lavender-blue-flowered Salvia comes from Southern Texas and has the same breeding as the famous Ultra Violet Autumn Sage. Although it needs warmer winter temperatures and has smaller foliage, it also does well in stressful conditions, including drought.
(Ultra Violet Hybrid Sage) Hardy is a word bandied about by gardeners and nurserymen. Its use is often exaggerated. But this fine hybrid deserves to be called "the hardiest Autumn Sage." It's Zone-5 hardy, drought resistant and has lovely, soft purple flowers. Ultra Violet is a winner.
(Red Sage, Chinese Sage, Dan-shen) The bright red, finger-like roots of Salvia miltiorrhiza have a long history in traditional Chinese herbal medicine.
(Kyushu Woodland Sage) We are in love with this short forest sage from Kyushu, Japan. Its clusters of large creamy flowers pale as fresh-churned butter begin blooming in September. Even when not blooming, its foliage is showy in a shady garden.
(Himalayan Cloud Sage) Nepal's Muktinath Valley -- a sacred site for Hindus and Buddhists -- is the place to go to see this majestically tall shade perennial in the wild. It grows at altitudes up to 14,000 feet and often emerges while the ground is still snowy.
(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.
(Big Pitcher Sage) As its scientific name indicates, this sage has very large flowers. They are almost two-tone, changing from deep violet to a light blue or white at their base where they are cupped by dusky purple calyxes.
(Turkish Cliff Sage) Spring into early summer, Turkish Cliff Sage produces erect, branching flower spikes 24 to 36 inches long that rise from basal foliage. They’re covered with whorls of pale pink blossoms with delicate white markings.
