(Giant Spreading California Purple Sage or Giant Spreading California Gray Sage) Looking for a large scale ground cover? One for poor soil, little to no water, howling winds or seriously hot sun? This Salvia leucophylla variety, collected in the wild and close to the ocean at Point Sal near Santa Barbara, may just be the plant for you.
Commonly known as Purple Sage for its flowers or Gray Sage for its silvery, velvety, foliage, Salvia leucophylla is a hardy Salvia species that is highly regarded for attracting small wildlife including songbirds, which love its tasty seed and the insects it attracts.
Amethyst Bluffs, which can grow up to 10 feet tall and 15 feet wide, is the largest clone of this species in cultivation. In most gardens it can be counted on being 6 feet tall and wide. It has dark pinkish-purple flowers that bloom in spring.
Amethyst Bluffs was collected in the wild, close to the ocean at Point Sal near Santa Barbara. It has a wider gardening range than the species, being cold hardy to at least 15 degrees F, it is worth trying in some Zone 7 areas. All this tough & hardy sage requires is well-drained soil and full sun.
We would use this shrub in the landscape even if it didn't flower, because its long, fuzzy, gray-green leaves with serrated edges are so appealing. Aside from being a great large-scale ground cover that takes minimal care, it is a handsome screen or border plant for dry gardens.
Here are some guidelines for success with this plant in your garden.

Exposure
Full Sun
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.
Full sun
Heat Tolerant
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
Fragrant
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
Zone(s) 8 - 10
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.

72 inches tall+
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.
72 inches tall+
72 inches wide+
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.

Ground Cover
Try this plant to control weeds, limit erosion, conserve soil moisture and add color to your landscape.
From short perennials that form dense mats spread by underground stoloniferous roots to thickets of medium-size shrubs, many Salvias are efficient ground covers.
Ground cover
Shrub
Shrubs are characterized not only by bushy foliage but also by woody stems.
Shrubby Salvias may be evergreen or deciduous. Some Winter-blooming, deciduous species lose their foliage during hot weather. Some Salvias, classified as subshrubs, have a combination of woody and tender, herbaceous growth.
Salvia shrubs range from tall, upright species to ground covers of short to moderate height. Their spread may match or exceed their height

Water Needs
Drought
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
Spring
This plant reaches peak bloom during Spring or flowers for much of the season.
However, it may begin flowering sooner. Some Spring-blooming Salvias begin flowering in Winter; others start in Spring, keep producing color through summer and may continue on into autumn and first frost. Still others flower only in Spring.
There is a great deal of overlap in blooming seasons for Salvias.
Spring
Wildlife
Honeybees
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
Honeybees
Butterflies
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.
Butterflies
Deer
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.
Deer resistant
Hummingbirds
Based on our experience and reports from customers, hummingbirds (Trochilidae spp.) love this plant.
Hummingbirds exist only in the Americas where their 300-plus species are particularly fond of the nectar in brightly colored Salvias from the Western Hemisphere. However, if favorites aren’t available, they dine on the nectar of most Salvias.
Hummingbirds repay thoughtful plantings by helping to pollinate your garden

Posted: Sunday, July 21, 2013 Synopsis: Quick Digs is a serial containing short posts focused on a central issue about Salvia gardening. The topic for the first series is Salvia groundcovers for weed control, and this is the first article. Great groundcovers help conserve soil moisture and leave little room for weeds to grow. This is true of many colorful, fragrant Salvias that spread freely. However, it may be that the essential oils creating the pleasant aromas of many Salvias are also helpful in suppressing weeds. Many researchers refer to this apparent trait as the “Salvia phenomenon.”
