(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.
This plant is widespread on the coastal hills and adjacent rocky hills of the South African Cape where it loves full sun. Used both as a culinary and medicinal herb by the native peoples of this area, it was adopted by Dutch colonials in the 18th century.
Hardy and drought-resistant, Blue African Sage can be a foundation planting in your garden or an unusual container choice. It is a butterfly favorite that blooms from late spring through summer with abandon. We love this deer-resistant Salvia and believe it should be used more widely.
Note: We have reason to believe this species may have greater cold tolerance than documented. Also, according to some taxonomists, the correct name for this species is now Salvia africana.
(North African Sage) This stunning herbaceous perennial has sky blue flowers on showy, branched spikes that grow up to 6 feet tall.
Native to North Africa and Southwest Spain, it is semi-deciduous. North African Sage appears compact until blooming from summer through fall. It's a surprising, spectacular addition to any perennial border. Plant it early for best bloom. After flowering time, you can cut it back to a low mound. We highly recommend this FBTS favorite.
(Mauretania Tingitana Sage) Native to Northern Africa and Saudi Arabia, this sage has a long history of cultivation going back 400 years and weaving throughout various countries in the Middle East and North Africa before arriving in Europe in the 1700s. It was first described scientifically in 1777.
Before the discovery of its Saudi Arabian connection in 1989, the origin of this heat- and drought-tolerant perennial was a hotly debated mystery. Was it native to Egypt, Syria, Aleppo, Tunis or Tangier?
Tingitana grows in a wide range of conditions and is particularly useful as a border or cut-flower plant in dry gardens. It branches freely and features flower spikes with large numbers of 1-inch-long, bicolor, yellow and lavender blossoms. The roseleaf-type foliage is lime green, heavily textured and fragrant.
Given full sun and well drained soil, this lovely sage forms a compact mound that also looks pretty in patio containers. This plant deserves to find a home in more gardens.
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.
Xeric plants are excellent for water conservation. They grow well in dry gardens with little to no supplemental watering once established. In fact, overwatering can harm these plants, which are native to dry environments such as deserts and chaparral.
At Flowers by the Sea, we identify all xeric plants with a blue plant marker that warns against overwatering. Here are some tips for growing and understanding our xeric, or blue tag, plants:
1) In a humid region, you may find it difficult to grow plants native to semi-arid and arid environments. Yet xeric plants may succeed if you have a persistently dry area, such as under a roof overhang or in the shelter of a tree.
2) Xeric plants are excellent for locations far from garden hoses, such as along sidewalks -- areas often referred to as "hellstrips."
3) Shipping is hard on xeric plants, which suffer from confinement in small containers as well as boxes. You may see some mold, spots on leaves or withered foliage when they arrive. But xeric plants perk up with proper care while hardening off in partial shade before planting.
4) When amending soil before planting, remember that xeric plants not only need excellent drainage but also flower better in low fertility soil. Fertilize sparingly and use a mix with more phosphorous than nitrogen to encourage flowering and discourage lax overgrowth of foliage.
5) Organic matter, such as compost, is an excellent soil amendment for xeric plants, because it keeps their roots healthy by improving aeration and drainage.
6) When your xeric plants are established, water infrequently to encourage deep root growth and to avoid fungal problems. However, it's a good idea to gently spray dust off foliage about once a week.
