Scrappy African Sage is a herbaceous perennial that is closely related and similar in appearance to Salvia disermas, another white-flowered South African species. "Scrappy," as well as the scientific appellation "radula," refer to the roughness of this drought-tolerant sage's hairy, lance-shaped leaves.
Growing anywhere from 2 to 5 feet tall with an average spread of 3 feet, Scrappy African Sage needs well-drained soil and prefers average watering depending on local conditions. However, it is ideal for dry gardens where it can be used in borders and for edging paths. It is also a longtime medicinal herb in South Africa and the subject of medical research concerning its anti-malarial and anti-bacterial properties.
The climate in much of South Africa is Mediterranean, which means wet winters and dry summers. So Scrappy African Sage grows particularly well in similar coastal climates. We highly recommend this sage for its beauty, toughness and adaptability to a new home by the sea.

Here are some guidelines for success with this plant in your garden.

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.
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
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.
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.
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 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.
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.
In the right locale, this plant survives and thrives despite minimal summer water.
Drought resistance is an important characteristic of xeriscapic – dry landscape – plants, a category that includes a multitude of Salvias. Many low-water Salvias are native to parts of the world with little rainfall all year or regions where summers are dry and winters are wet.
Nevertheless, there are also drought-resistant Salvias for places such as Florida where winters are dry and summers are wet.
Blooming Season
This plant reaches peak bloom in Summer or flowers for much of the season.
Lots of Summer bloomers start flowering in Spring; others begin in Summer and keep up the show of color until frost.
There is a great deal of overlap in blooming seasons for Salvias.
Wildlife
Honeybees love this plant’s nectar. As a honeybee burrows down into a Salvia’s nectar-rich flowers to reach dinner, it accidentally gathers pollen and drops it on the stigma of that blossom or of ones on other nearby Salvias. Fertilization results in seed production.
By growing honeybee favorites, you attract these helpful pollinators to all your flowering plants and increase productivity
This plant attracts butterflies whether for nectar or as a host for their caterpillars. Some butterflies feed on a limited range of flowering plants and only lay eggs on one kind of host plant. Salvia nectar lures adult butterflies. Placing host plants, such as Milkweeds (Asclepias spp.), next to nectar plants builds butterfly habitat. In exchange, the butterflies improve fertility in your garden through pollination.
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.
(Pilgram's Rest Pink Sage) Spring into summer, this heat-tolerant sage from South Africa produces lilac and white blossoms with profuse, fragrant, gray foliage. It's the burgundy calyxes, which turn a rusty pink after the flowers blossom, that give this sage part of its common name.
(Rough Blue Sage) Honeybees and butterflies love this deer-resistant shrub, which grows wild on the southwestern Cape of South Africa. It is a member of the most diverse plant community in the world, the fynbos -- an Afrikaans word, meaning "fine bush" and referring to scrub plants or shrubbery.
(Atlas Mountain Sage) Tawny looking from a distance, the Atlas Mountains of northern Africa are home to an abundance of greenery, including the lovely Salvia interrupta. So the mountains contrast sharply with the Sahara Desert, which they border.
(White Mischief Mexican Bush Sage) Profuse white blossoms and true white velvety bracts make the flowers of this South African hybrid a lovely choice for a wedding. In our experience, many of the plants sold as White Mischief are not the real thing. This tough, compact, long blooming sage is.
(Blue African Sage or Blousalie) A handsome, densely branched shrub with small, gray leaves, this Salvia puts on a show when in full bloom. The pale blue flowers bloom on foot-long spikes that cover the plant. Each flower has a large, trumpet-shaped, green-and-red bract at its base.
