(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.

Confusion about watering of plants is understandable, because moisture needs vary so much from one species to another. It also varies based on your local growing conditions. Ask Mr. Sage, a regular feature of the Everything Salvias blog at Flowers by the Sea Online Plant Nursery, explains the differences between the labels drought resistant, average water and water loving classifications for estimating water needs. Some FBTS average water plants also grow well in dry or damp settings.

Here are some guidelines for success with this plant in your garden.
Click on an individual icon for more detailed information.
Exposure
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 can handle extreme heat.
Full-sun Salvias that don’t like any shade are among the most heat tolerant. Heat-loving Salvias also are often drought tolerant. Moisture-conserving features, such as fuzzy leaves, help them stay perky at high temperatures.
Heat-tolerant Salvias are fine choices for western and southern exposures.
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.
Garden Uses
When growing a fragrance garden, this is a good selection.
Most Salvias have pleasant scents, but some are intoxicatingly fragrant. Some are short enough for border plantings that release a heady perfume as you brush against them when strolling along a path. Other taller types make good landscape highlights, particularly by doors where their scent can be enjoyed on entry and exit.
Growing Habit
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.
Water Needs
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.
Blooming Season
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.
Wildlife
Unless local forage is in short supply, most deer likely will avoid this plant.
It appears that deer dislike Salvias, in general, due to their volatile oils that make the plants so fragrant and savory in cooking. However, the only completely deer-proof plants are the ones grown beyond reach.
