Sometimes, when defining a plant, it is helpful not only to say what it is but also what it is not. Herbaceous perennials are not woody. They have soft stems and die to the ground annually, sending up shoots again in the new growing season.
Although perennial generally refers to any plant that returns for more than two growing seasons, it is a term that the horticulture industry -- and our catalog -- primarily applies to herbaceous species even though the deciduous, woody Salvias also refresh annually.
In contrast to herbaceous perennial Salvias, the woody kinds of sage are referred to as shrubs and subshrubs. Shrubs are plants with stems that are woody overall. Sub-shrub Salvias combine woody and tender herbaceous stems.
Some Salvia species, such as Autumn Sage (Salvia greggii), are evergreen shrubs -- the kind that are in a constant state of foliage loss and renewal -- in warmer USDA zones and subshrubs in cooler parts of their range. But true herbaceous perennial Salvias almost always die to ground at the end of their growing season. End of season depends on whether an herbaceous perennial is dormant in winter or dormant in summer as with winter-growing species originating in Mediterranean climates.
Flowers by the Sea grows many herbaceous Salvias in a rainbow of flower colors and a wide variety of bloom times, including cold-hardy species from America, Asia and Europe. Others come from warmer climates, such as Africa, the American South, Central and South America, Mexico, the Mediterranean and South Africa.
One major way in which care of herbaceous species differs from that of woody sages concerns clean up. Whereas woody sages are hard pruned at the beginning of their growing season, the spent foliage of herbaceous species is removed at the end of their season. Also, many herbaceous species can be encouraged to bloom twice if pruned mid-season.

(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."

(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.

(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.
(Dot's Delight Bicolor Gentian Sage) This sage turns heads, because its large, white and blue bicolored flowers make it a unique variety of Gentian Sage. Developed in the UK, Dot's Delight is less vigorous and less sun tolerant than other varieties of the species. This is our own tested seed strain of this rare plant.
(Guanajuato Giant Gentian Sage) At 3 inches long, the flowers of this Gentian Sage are the largest of any we grow. Guanajuato Giant is also unique for its tall, upright growth and heavily textured foliage. This is our own tested seed strain of this rare plant.
