Victoria Blue salvia plant is valued for the deep blue flowers that run up and down its showy spikes, which can be up to 8 inches long. Native to North America, the fast-growing plant is best started in early spring and can be made to bloom all summer long with proper care.

Take advantage of Victoria Blue salvia's long blooming season and vibrant color by using the plant to fill holes in your sequence of bloom (they're also a favorite of pollinators like hummingbirds, butterflies, and bees). It's also a good idea to deadhead the blooms if you are striving for the best flowering display possible, though some gardeners prefer to let the flowers go to seed, hoping for naturalization. Divide the plant in spring if you are growing as a perennial and you wish to gain extra plants for use in other areas of the yard.

Victoria Blue Salvia Care

Plants brought home from the garden center should be installed in the ground only after all danger of frost is over in your area.

It is a good idea to deadhead them if you are striving for the best flowering display possible. Some gardeners prefer to let the flowers go to seed, hoping for naturalization, in which case they will avoid deadheading. Divide them in spring if you are growing the plants as perennials and you wish to gain extra plants for use in other areas of the yard.

These plants do tend to get powdery mildew on their leaves. If you are growing them as perennials, you may not consider this a big problem, since the powdery mildew does no real harm and the plants will come back just fine next spring. But if you are growing them as annuals, you have a small window of opportunity in which to enjoy them, and powdery mildew would spoil your enjoyment. Since powdery mildew is a fungus, and since fungi like moist conditions, the key to preventing it is good air circulation:

  • Provide your plants with good air flow by giving them enough space (do not plant them tightly together). Good air flow helps the foliage dry off after it rains. Since plant width is up to 18 inches, space them at least 18 inches on center in a mass planting of Victoria Blue salvias if avoiding powdery mildew is your goal.
  • When watering, do not spray them from overhead. This gets the foliage wet and invites fungus. Instead, run your garden hose so that the water is directed at the base of the plants, at ground level.

Light

Grow these plants in a full-sun area in the North. In hotter climates, a bit of afternoon shade helps protect the plants from intense sunlight.

Soil

The main requirement is that the soil be well-drained. While it is not ideal, they will tolerate clay soil to some degree.

Water

Although they are drought-tolerant perennials once mature, do not forget to water young plants, which have more trouble with dry conditions. Since they last only one growing season in the North (which is not long enough for them to become mature), Northerners will have to water them regularly if they expect to get a good display of blooms.

Fertilizer

These plants do not need much fertilizer. Work compost into the soil of your planting bed every few years for them. 

Uses for Victoria Blue Salvia in Landscaping

Because of their showy, long-lasting flowers, they are often treated as bedding plants and massed together to form a "sea of blue," especially in the North. In round container gardens, install a Victoria Blue salvia plant in the middle, and let shorter plants in complementary colors trail over the edge, such as white sweet alyssum (Lobularia maritima). For those who like to bring the garden inside, the flowers can be used in cut-flower arrangements or dried for a longer-lasting display. They are also suitable for cottage gardens.

The deep violet-blue color of Victoria Blue salvia's flowers is no doubt the plant's best feature, making it an excellent choice in red, white, and blue floral color schemes for two U.S holidays during the warm-weather months: Memorial Day (in late May)​ and Independence Day (July 4).

Match them with sun-loving perennials that flower in yellow or orange for a nice color combination. Examples of good companion plants for them are:

In terms of their relationships with wildlife, Victoria Blue salvia flowers attract hummingbirds. Plus they are plants that attract butterflies and bees (bees tend to be drawn to flowers of a blue color). Luckily, they are deer-resistant perennials. Add this tender perennial to pollinator gardens, and enjoy the show, or plant them near veggie gardens to boost pollination of crops.
