(Bog Sage) Highly adaptable, Salvia uliginosa is ideal for the beginning sage gardener. It isn't fussy about soil type, sun exposure, drainage or frequency of watering.
This fragrant sage's common and scientific names don't communicate its beauty or growing range. Both names refer to the boggy conditions in which it grows in the wild in Argentina, Brazil and Uruguay. However, although it appreciates moisture, Bog Sage also does well in dry conditions that cause this stoloniferous plant to spread less.
Lovely sky-blue blooms, with white beelines on the upper and lower lips, top the many slender, graceful stems from summer to fall. When swaying in the breeze at the back of a perennial border or as part of a screen, Bog Sage is a pleasing sight for butterflies, honeybees, hummingbirds and humans alike.
Although it has an average height and spread of about 40 inches with flower spikes making it a bit taller, Bog Sage sometimes can reach heights of more than 72 inches, according to Mississippi State University.
Partial shade is preferable, but Bog Sage also grows well in full sun in all but the hottest and most arid environments. Cold and heat tolerant, it grows well in regions ranging from the arid Rocky Mountain West to the humid Deep South. Give it partial shade if possible. Full sun is fine in all but the hottest and most arid environments. We always sell out of this plant early in the season.
These are species whose stems never develop a woody character and that either die to the ground or loose leaves and become unsightly at the end of a growing season. This group includes both hardy and tender types. Many of the tender forms are grown as annuals in cold winter areas.
Pruning is both an art and a science. It takes practice, experience and learning from your mistakes to become a proficient pruner. The pruning information about this plant should be considered as a guideline for getting started. Your particular climate, soils, watering and fertility schedules, sun exposure, space requirements and weather are all factors that influence how and when you choose to prune. We’re providing a starting place for you, and over time you will learn the particularities of this plant in your garden. Don’t be afraid to get started – Salvias, in general, are quick to rebound if inappropriately pruned.
Deadheading – the removal of spent flowers, is a practice that will always benefit the plant’s health and appearance. This can be done at any time. Pruning involves removal of entire stems of spent growth. Becoming "spent" means that flowering stems stop blooming and begin going to seed.
During the spring and summer, you can completely cut to the ground any stems that have finished blooming and are becoming unsightly.
In mild climate areas, growth can be so rapid that the entire plant becomes messy and spent mid-way through the season. In this case, it can be cut back close to the ground – given a short “haircut”. The result usually is fresh, vigorous new growth and another round of flowering.
(Bitter Mexican Sage) Hummingbirds love this heat-tolerant Salvia, which is one of our best choices for shady, moist areas. The large-lipped, baby-blue flowers with white striations bloom from late summer through fall.
This compact shrub grows well in the garden or in a container, especially where it will receive morning sun and afternoon shade or partial shade all day. In its native Mexico, it is used as a folk remedy for a variety of ailments. We love its grace and beauty in the garden!
Vivid deep violet flowers bloom from summer into fall and contrast prettily with the bright green, rumply foliage of this tall sage from southeastern Mexico. Belgian botanist and orchid lover Jean-Jules Linden was the first to record its discovery in 1838, according to records on file at Britain’s Royal Botanic Gardens, Kew.
Linden shares credit for this sage with two peers who also were researching the botanical treasures of Mexico -- botanists Henri Guillaume Galeotti of France and Martin Martens of Belgium. The website MexConnect notes that Linden and Galeotti were part of a scientific entourage that climbed Mexico’s highest peak -- the volcano El Pico de Orizaba, which rises 18,853 feet above sea level – near Veracruz in 1838. Perhaps that is where they encountered this heat-tolerant, yet water-loving sage.
By six years later, the plant was published as Salvia biserrata M. Martens & Galeotti. Who knows why Martens’ name is attached to the species and not Linden’s? It is a tantalizing mystery about a tough, attractive plant for which little information is available.
However, we do know that this herbaceous perennial grows rapidly up to 5 feet tall and 3 feet wide. It does well in either sun or partial shade and loves water and rich, well-drained soil. We also know that hummingbirds love it, but deer do not. We think you would enjoy it in borders, background plantings, moist areas of the yard, patio containers and seasonal flowerbeds.
Note: The name of this plant could be suspect, as not all botanists agree. Whatever the name, this is a great summer Salvia.
(Forysthia Sage) This statuesque perennial grows up to 10 feet tall, but spreads only 3 feet wide. It is a late bloomer from Mexico's Sierra Madre Oriental mountains where it grows at altitudes of 4,000 to 5,000 feet and tolerates temperatures down to 20 degrees F.
Short periods of colder temperatures don't kill this tough sage. When knocked out by frigid weather, it usually comes back from root stock. A single plant forms a multi-stemmed thicket through slowly spreading rootstock, but can easily be kept tidy by removing unwanted stems.
Give this sage morning sun and afternoon shade as well as ample water. From fall until frost -- or into spring in mild winter areas -- it will reward you with buttery yellow flowers that make this shrub look like a Forsythia from a distance. But get up close and you will notice that it has roughly textured, heart shaped leaves as well as thick, square stems.
You can grow Forsythia Sage as a screen, border or background plant. It even does well in containers. We love to plant Bog Sage, Salvia uliginosa at its base for a bright blue floral contrast.
(Arrowleaf Sage) Brilliant royal blue flowers and unusual foliage attract the eye to Arrowleaf Sage. This large herbaceous perennial is found at elevations up to 10,000 feet in the Cordillera de los Andes of Chile, Ecuador and Peru.
Sagittata refers to the arrowhead shaped leaves, which are deeply textured, lime-green and woolly on the undersides. The flowers rise up 1 to 2 feet on dark, leafy spikes from summer into fall.
This sage is adaptable about settings ranging from full sun to partial shade, but needs at least a few hours of strong sunlight daily to bloom well. It also likes well-drained soil that’s high in organic matter, regular watering and a light feeding once or twice a month during rapid growth.
Arrowleaf Sage's habit of spreading via suckers makes it a good groundcover. However, it needs some partial-shade time to do this. It also works well in perennial borders and containers as well as along pathways.
For the best shape and most profuse bloom, cut this sage down to its lowest few active growth nodes in March.
Hummingbirds love Salvia (sage) nectar and are attracted to it by the bright colors of tubular sage blossoms. In particular, these little whirlybirds can easily spot flowers in the red spectrum, which is prevalent among sages. Here are some hummingbird gardening tips.
If you live in suburbs or rural areas where deer plunder gardens, Salvias (sages) can be part of your plan for discouraging these hungry visitors. Here are some tips.
