Zone 5 Salvias are generally hardy to -20 degrees F. They are mainly herbaceous perennials with soft foliage that dies back to the ground for winter. A few are subshrubs -- semi-woody perennials. When selecting these for your garden please consider your winter soil moisture, as varieties from dry winter climates will not necessarily overwinter successfully in wet winter soil.
(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.
(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.
(Purple & Yellow Yunnan Sage or ji ye shu wei cao) Confusion about this plant's scientific name cause it to appear in some sources as Salvia flava var. megalantha. Whatever you call it, this Chinese species from Yunnan Province has enchanting yellow and purple flowers that attract viewers as well as honeybees.
(Caucasus Sage) This hardy ground cover sage grows 4 to 12 inches tall and 12 inches wide. The velvety white fur of its foliage aids moisture retention. Its soft, royal purple flowers make it stand out. We think this Salvia deserves to spread far and wide.
(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.
(Autumn Enchanter Japanese Woodland Sage) Salvia glabrescens ‘Autumn Enchanter’ has bicolored orchid pink flowers that are larger and bloom earlier than those of S. glabrescens ‘Shi Ho’. Autumn Enchanter is also more floriferous, blooms longer, and grows more rapidly with greater vigor.
(Autumn Equinox Japanese Woodland Sage) Although similar to the Japanese native Shi Ho Woodland Sage, Salvia glabrescens 'Autumn Equinox' has much larger flowers that are bicolored purple and bloom earlier. Autumn Equinox is also more floriferous, blooms longer, and grows more rapidly with greater vigor.
(Makino) We would grow this rare clone of the woodland Japanese native Salvia glabrescens even if it never flowered, because the arrow-shaped foliage is so lush, toothed and colorful. As they age, the arrow-shaped leaves transform from yellowish green to dark green.
(Jupiter's Distaff) Easy to grow and adaptable to a wide range of conditions, this native of Europe and Asia is our best tall, yellow-flowering perennial. Although its common name compares the flower spikes to wool spindles, they look more like glowing sceptres.
(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.
(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.
(Shangri-la Sage) Take a close look at Salvia moorcroftiana x indica ‘Shangri-la’ and you’ll notice that its lavender flowers have lighter lower lips with deep purple freckles.
(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.
(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.
(Siberian Sage) Deep violet flowers surrounded by burgundy bracts form a handsome contrast with the pebbly, mint green foliage of this drought-resistant sage. It comes from the Central Asian steppe, which is similar in climate and geography to America’s high plains.
(Lilac Sage) We try not to brag too much, but this is our own variety of Salvia verticillata from home-grown seed, and we think it is spectacular. Butterflies and honeybees also are in love with this long-blooming perennial beauty.
