Some plants are just great performers in the garden. When we feel that a particular plant deserves top accolades, we give it the Best of Class designation, along with this icon. When you see this you can be sure you have found the best of its type.
We do our best to keep these plants in stock at all times, but many are in high demand and availability can be spotty.
(Heart Leaf Sage) From the rich plains of Northern Argentina comes this delicate looking sage with heart-shaped leaves and pale blue flowers so perfect they seem to be molded in wax. Although a slow grower that requires good garden culture, this Salvia is exquisite.
Heart Leaf Sage needs fertile soil that is rich in humus and well drained. It grows well in the ground or in a container. Site it in a warm, sunny spot where it can receive partial shade and no reflected heat. Water and fertilize well. Be patient, as it seems to take a year or more to settle in and become robust. Then sit back and enjoy the lovely foliage and 1-inch-long, striped flowers.
This perennial sage was found by Rolando Uría in Chaco, Argentina in 2009 and is one of the rarest Salvias in the world. It is quite slow to increase, but we highly recommend its beauty.
(Vatican White Clary Sage) Clary Sages are well known for their use in folk remedies, aromatherapy and cosmetics. Large white bracts frame the spectacular white blooms of this cultivar on 5-foot-tall spikes. It is a delight for honeybees and butterflies.
(Stem Clasping Violet Sage) Like a candelabra lit up with whorls of violet blossoms, the erect, branching flower spikes of Salvia amplexicaulis make this native of Southeastern Europe shine. On the Grecian island of Thassos, it brightens areas near the beach.
(Rocketman Russian Sage) A cloud of cool, lavender-blue flowers shoot upward from the fine-leafed, gray-green foliage of Salvia yangii ‘Rocketman’. This is a shorter, more upright form of Russian Sage, which was known botanically as Perovskia atriplicifolia until 2019 when the species was reclassified as a Salvia.
(Elk Super Scarlet Rooster Sage) From the mountains of Mexico we have this stunning Sage, which seems never to be out of bloom. A superior hummingbird plant, the warm orange flowers that cover this shrubby perennial make it a standout in the garden.
We based our analysis of this plant’s floral and foliar color on the internationally standardized color system published by the U.K.’s Royal Horticultural Society. Called the RHS Large Colour Charts, this publication is a boxed set of color swatches arranged in fans and containing all the colors that RHS has identified in horticulture. RHS gives each color a common name and code number.
Each swatch has a small hole punched into it. We place the swatch over a flower petal and compare the blossom’s color to that of the card. When using RHS colors to compare plants that you want to combine in a flowerbed, in bouquets or in some other manner, RHS says to view them indoors in north light. If you are matching our digital swatches to flowers already in your garden, pluck two or three fully open blossoms of each plant that requires analysis.
You may find that the plant you receive from FBTS varies somewhat in color from what appears in our color analysis or our photograph due to a number of factors, including:
Finally, RHS notes that you shouldn’t attempt color matching when your eyes are fatigued.
This plant needs or tolerates more than six hours of intense sunlight daily. Many Salvias only thrive in wide-open locations where they receive long hours of full sun. However, full-sun species sometimes tolerate a bit of partial shade. Or a Salvia that loves partial shade may be amenable to spending part of its time in full sun.
In general, this sun/shade adaptability shows up in Salvias that do best in cooler climates when grown in full sun and thrive in hot climates when partial shade is available. So full-sun Salvias sometimes are also categorized as partial-shade plants and vice versa.
This plant grows well in partial shade, such as the kind on the edge of woodlands or under deciduous trees with breaks in the foliage through which dappled sunlight penetrates. Many Salvias thrive in partial shade, including ones that spend part of their day in full sunlight. Some species need partial shade to overcome severe heat and dry soil.
Plant hardiness Zones defined by the U.S. Department of Agriculture tell you the minimum temperatures a plant can withstand in your garden. The USDA divides the nation into winter climate areas from coldest (Zone 1) to warmest (Zone 11).
However, it is sometimes possible to grow a Zone 6 Salvia as a perennial in Zone 5 if you provide preferential care, such as winter mulching and a location sheltered from harsh winds. In contrast, a Zone 9 Salvia may act like a perennial in Zone 10 if given a bit of shade or extra water.
To create a harmonious landscape plan, it is important to consider the heights of individual plants.
Height also affects function. Short Salvias often make excellent ground covers that conserve soil moisture and discourage weeds while also brightening your yard. Medium-height Salvias, such as ones 36 inches tall, often are ideal border plants. A tall Salvia planted singly can highlight a landscape; multiple plantings can form an attractive screen.
By considering the width of a plant, you can determine how many to place in a row or what other plants to grow with it.
For example, a narrow, moderate-height Salvia may look good interplanted with bushier species, kind of like Mutt and Jeff.
In contrast, wide-spreading Salvias are economical for hiding lengths of wall and fence or for creating hedge-like divisions in a yard.
Plant this herbaceous species in the USDA Zones where it grows as a perennial, returning year after year.
After dying back to the ground at frost, herbaceous perennials emerge in the Spring with soft, new growth. A Salvia that is perennial in one region, may be an annual in another depending on local conditions, such as winter temperatures.
If you live in USDA Zone 5, for example, Salvias in our catalog cited as growing well in Zone 5 or lower will be perennial. Those cited as doing well in Zones 6 or higher may do well in Zone 5, but generally will act like annuals coming back from seed instead of the parent plant’s roots.
This plant needs regular watering based on what is appropriate to your local conditions.
In some extremely hot, arid climates, this may mean daily watering in Summer. Although many drought-resistant Salvias survive on little to no watering due to local rainfall and deep roots meeting their moisture needs, others need regular doses. The size and frequency of the dose depends on your climate.
This plant thrives on or at least tolerates lots of water, especially when soil is well drained. They are generally not suitable for poorly drained soils.
A number of Salvias hold up well in areas where rainfall is a regular occurrence. Some even tolerate boggy conditions but only for a brief time. These are usually top-notch plants for regions of the country, such as the Southeast, where summers are soggy.
This plant reaches peak bloom in Fall or flowers for much of the season.
It may begin flowering much earlier in the year. Bloom time for some Salvias lasts from Spring till first frost. Others begin flowering in Summer and continue into Fall. There are also Salvias that don’t bloom until late Fall and continue into Winter if grown in mild-Winter areas.
There is a great deal of overlap in blooming seasons for Salvias.
