(Tamaulipas Sage) Deep purple flowers, strong stems and attractively textured, gray-green foliage make this sage useful in the drought-resistant Salvia garden. Rising up to 5 feet tall and spreading feet wide, it is a fine backdrop.
Although from Northeast Mexico, the botanical appellation "pennellii" indicates that this sage was named after botanist Francis Whittier Pennell (1886-1952) who specialized in the Snapdragon family and also conducted field work for the New York Botanical Garden in South America.
This heat-resistant sub-shrub acts like a shrub in areas where winter temperatures seldom sink past about 25 degrees F. In colder areas, it grows like a herbaceous perennial that dies back after a frost.
Use this plant at the rear of a border or in a dry wild garden. It's a bit rowdy -- not terribly well mannered about sprawling -- but a vigorous grower. If you value drought resistance, heat tolerance and late-season bloom, this rare plant can do the job. We think it should be more widely grown.
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 - 11
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.

48 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.
48 inches tall+
48 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.

Perennial
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.
Perennial
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
Shrub
Water Needs
Average
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.
Average water
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
Summer
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.
Summer
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
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.
