Despite doing a good job of tolerating clay soils, Santa Rosa Island Sage prefers well-drained soil in full sun. Water it regularly to see fast growth or don't water it at all once established. This is a tough, drought-tolerant plant. Either way, it is a charming border shrub, and we highly recommend it.
Cold weather note: This plant can tolerate a few hours at 0 degrees F, but cannot endure the longer cold spells of Zone 7a winters.

Flowers by the Sea grows a number of native California sages, including threatened species such as the woody perennial shrubs Santa Rosa Island Sage (Salvia brandegeei) and Island Pitcher Sage (Lepechinia fragrans). Elusive is one adjective to attach to both plants, because they are rare in their native Channel Islands homelands off the coast of Southern California where they are endangered.

Native plants are the best ones for local conditions. But sometimes boundaries designating what is native may be artificial. Here are five outstanding Xeric Salvias for Southern California, including one, not far over the Baja border, that offers intense drought resistance and violet-blue flowers.

Native plants, including California's many indigenous sages, are like the boys or girls next door who were overlooked until outsiders discovered their good looks and other fine attributes. For the longest time, native species didn’t get respect in home gardening – a sizeable oversight considering that California alone has more than 5,500 native plants. Natives are roughly defined as species that were growing in America before European colonization. Flowers by the Sea cultivates hardy, drought-resistant California Salvias that are native to a broad swath of the West Coast ranging from Northern Baja to Southern Oregon. The California natives detailed here are all drought resistant and many tolerate heat. They are well suited to waterwise, xeriscapic landscapes, including dry gardens in which plants must survive despite almost no supplemental watering.

Here are some guidelines for success with this plant in your garden.
Click on an individual icon for more detailed information.
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.
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.
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.
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
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.
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.
This plant flowers throughout Winter.
Many winter-blooming Salvias begin flowering in late Fall and continue on into Spring; there is a lot of overlap in blooming seasons for Salvias. Winter bloomers include evergreen as well as deciduous perennial Salvias.
Depending on type, they grow well in USDA Zones ranging from 8 to 11 with some tolerating the chill of Zone 7.
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
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.
