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.
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.
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.
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.
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.
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
(Shangri-la Sage) Take a close look at Salvia moorcroftiana x indica ‘Shangri-la’ and you’ll notice that its lavender flowers have lighter lower lips with deep purple freckles.
(Greek Sage) Most of the dried culinary sage sold in the United States is Greek Sage. Frescoes on the island of Crete dated to 1400 BC depict this plant, which was used by the Phoenicians and Greeks for cooking and medicine. It is an ancient and beloved friend of mankind.
(Sacred White Sage) Bees, hummingbirds and spiritual blessings are all connected to Salvia apiana, an elegant shrubby sage that is an important herb to indigenous Californians. It deserves a place in salvia gardens that can meet its demands. Stiff and almost fleshy, its leaves are tight rosettes of brilliant, silvery green that is almost white.
(Yugoslavian Cut Leaf Sage) This is a rare Baltic steppe plant that grows beautifully in sunny locations with little water and excellent drainage. It is endemic to a the Orlova Brdo region of the Former Yugoslav Republic of Macedonia.
(Woolly White Sage) Salvia candidissima has tidy, upright stems covered with whorls of creamy white blossoms shaped like tiny parrot beaks. They rise from a mid-green rosette of leaves that become fuzzier and whiter as summer heat increases.
