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.
(Heatwave Red Mountain Sage) Compact and small, this Mountain Sage is another fine groundcover for Southern California, the Southwest and Texas. Similar to Salvia microphylla 'Heatwave Glimmer', it not only survives but thrives in extreme heat.
(Brilliance Pink Mountain Sage) Long blooming Salvia microphylla 'Heatwave Brilliance' produces prolific quantities of deep reddish-pink, or cerise, blossoms along with dense, mid-green foliage.
(Glimmering White Mountain Sage) Heatwave Glimmer isn't a mirage. It is a Salvia microphylla that tolerates extremely hot climates as well as cooler regions. It doesn't just survive; it thrives in the heat of Southern California, the Southwest and Texas.
(Scorching Pink Mountain Sage) Compact and small, this Mountain Sage is another fine groundcover for Southern California, the Southwest and Texas. Similar to Salvia microphylla 'Heatwave Glimmer', it not only survives but thrives in extreme heat.
(Hot Lips Sage) What a winner for fascinating flowers! Hot Lips Sage has solid red, solid white and two-tone combinations all on the same plant and often at the same time.The variations are random. You might say that this shrubby sage is mixed-up, but its confused coloring makes it highly desirable.
(Trinity Mountain Sage) Heat and drought tolerant, this Salvia microphylla is native to Northeastern Mexico where summers are dry and temperatures can rise to more than 100 degrees F. It can survive winter temperatures down to 0 degrees.
(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.
(Big Orange Mountain Sage) When temperatures are cooler in spring and fall, the persimmon-orange flowers of this large Mountain Sage darken. Gray-green foliage, bright green calyxes and reddish-green stems add to the plant's fascinating look, which mixes well with yellows and blues.
(People's Park Mountain Sage) Sometimes nature can be rebellious. This is one the Mountain Sages known as the Turbulent Sixties Series developed from an outlaw cultivar of the Southwestern native Salvia microphylla. Monterey Bay Nursery (MBN) named their accidental hybrid ‘Berzerkeley.’
(Red Velvet Mountain Sage) This is one of the most intense red-flowering variety of Mountain Sage we grow. Medium-sized flowers are profuse on this large, vigorous plant -- particularly in spring and fall. Dark stems and calyxes intensify the plant's drama along with glossy green foliage.
(Royal Bumble Mountain Sage) Almost black, the stems and calyxes of this UK hybrid form a pleasing contrast with its medium-size scarlet flowers and glossy green leaves. Bloom time is spring to fall. This Mountain Sage suckers freely and forms a dense clump.
(St. Charles Day Mountain Sage) Especially in spring and fall, masses of red-violet flowers bloom amid the silvery green foliage of Salvia microphylla 'San Carlos Festival'. Put this one into the "must have" column.
(Telegraph Avenue Dwarf Mountain Sage) Here’s another member of the Turbulent Sixties Series of Southwestern Mountain Sages (Salvia microphylla), which developed from one of nature’s rebels – an accidental hybrid that Monterey Bay Nursery (MBN) named ‘Berzerkeley’ after finding it taking a stand in the nursery’s gravel paving.
(Red Sage, Chinese Sage, Dan-shen) The bright red, finger-like roots of Salvia miltiorrhiza have a long history in traditional Chinese herbal medicine.
(Royal Purple Autumn Sage) Salvia muelleri is related both to Autumn Sage (S. greggii) and Mountain Sage (S. microphylla), which are closely related species.
(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.
