Are Salvias Perennial? Plus 6 Salvia Alternatives

What is the difference between annuals and perennials?

Annuals are flowers that grow, flower, seed, and die off in a single year.

Some plants cannot tolerate frost, so in cooler zones, they will die off. Some plants can survive warmer winters, so an annual in a cold zone may be considered a perennial in a warmer zone.

Perennials are plants that grow, flower, seed, and return year after year.

Many perennials are frost-hardy meaning that they will survive cold weather. While their green, vegetative growth may die off in winter, the roots keep living. Then in spring or summer, the plant will grow and bloom just as it did the year before.

Are all salvias perennial?

The answer is: it depends.

Salvia encompasses a large family of plants from herbal sage to ornamental annuals. The herb sage, or Salvia officinalis, is a perennial in most USDA zones. Salvia splendens, the ornamental red-flowered bloomer, is an annual in almost every USDA zone.

Are any salvias perennial?

Yes, herbal or culinary sage is perennial in most areas of the US. Ornamental salvias are perennial only in warmer growing zones. If you live in a warm climate, most salvias will be perennial. If you live in a very cold climate, no salvias will be perennial (unless you bring them indoors for winter).

What zones are salvias perennial in?

Here is a breakdown of some salvias and what USDA zones they can survive in. Most salvias will survive in zones 8 through 10 and few varieties will survive in cooler zones. This is not an exhaustive list, but most salvias will be similar in zonal requirements.

  • Pineapple sage (Salvia elegens) is a salvia perennial in USDA zones 8 to 10
  • Scarlet sage (Salvia splendens) is a salvia perennial in USDA zones 8 to 10
  • Mealycup sage (Salvia farinacea) is a salvia perennial in USDA zones 8 to 10
  • Mexican bush sage (Salvia leucantha) is a salvia perennial in USDA zones 8 to 10
  • Anise-scented sage (Salvia guaranitica) 'Black and Blue' is a slavia perennial in USDA zones 8 to 10
  • Rosemary (Salvia rosmarinus) is a salvia perennial in USDA zones 8 to 10

  • Yellow Japanese Sage (Salvia koyamae) is a salvia perennial in USDA zones 5 to 9
  • Herbal sage (Salvia officinalis) is a salvia perennial in USDA zones 4 to 8

How do I take care of my salvias?

Salvias are easy to take care of and are a low-maintenance plant.

Salvias are somewhat drought and heat tolerant. This means they can grow in full sun and slightly sandy conditions. That being said, they can tolerate a wide range of conditions from moderate clay soil to partial shade.

Here are some key points to consider when growing your salvias:
  • Plant level with the soil, do not cover the stem or leaves with soil
  • Plant in the front or middle of flower beds, in containers, or hanging baskets
  • Plant in groups for a fuller appearance
  • Leave flower heads on in the fall to allow for seeding, this encourages their return the following year (not always will they self-seed, but it's worth testing)
  • Collect and store seeds for the following year

How do I keep my salvias blooming?

Salvia is a beloved flower. Why? Because they have many repeat blooms, often all summer long! For maximum flowering we recommend dead-heading.

Deadheading is the removal of dead or spent flowers from the plant

Deadheading encourages more blooms. When a flower dwindles, the plant works to create seeds from that flower. A lot of energy is spent on making seeds.

When the dead flowers are removed, the plant can redirect its energy into creating new flowers. This also helps strengthen the root system. It takes a bit of work, but the result of having more, vibrant blooms is well worth it.

It is a beautiful and beneficial plant with numerous advantages in landscaping projects. This herbaceous perennial belongs to the Saxifragaceae family and is admired for its delicate bloom spikes and attractive foliage. One of the primary benefits of incorporating it into landscaping is its captivating appearance. Foam Flower (Tiarella cordifolia), the Allegheny, is a gorgeous spring wildflower with feathery white spires that look lovely in sun-dappled gardens. With time, its foliage will form colonies with an excellent ground cover in shady spots. Where Foam Flower Can Be Found  It is native to wooded areas in eastern North America. This perennial can be found on seeps and stream banks, by creeks, in clearings, and under maple, hemlock, and white cedar trees. Along the eastern coast, it starts blooming in mid-March and continues to blossom through April. It owes its name to the sprays of tiny white to pinkish blooms that cover its three- to four-inch-long racemes. These delicate blossoms float around the tips of their long, graceful stems, which rise one to three feet above mounds of low-growing leaves. After it fades, the plant's foliage stays lush and glossy. The plant's bright green leaves grow up to four inches wide and usually have three to five lobes. The leaves' shape, color, and pattern can vary depending on the cultivar. They may stay evergreen in warmer climates, but their leaves and rosettes often turn red and bronze in the fall when temperatures cool down. Foam Flower Loves Shade Tiarella cordifolia brings soft, gentle intrigue to shady spots in your landscape. These blooms work beautifully in ornamental, wildflower, and woodland gardens beside ferns and blooms like Solomon's seal, dwarf crested iris, and bluebells. It adds a magical quality to small and mass plantings, grows under trees, and suits spacious pots and planters well. It also makes a lovely border or ground cover. It can be propagated by dividing and replanting the roots in late fall or starting from seed indoors, around ten weeks before the last spring freeze. Once the frost has parted, you can plant the seedling outside. It lures bees and other pollinators to your landscape, making them a valuable addition. Some small mammals eat its seeds for nourishment. Foam Flower Adds Whimsical Charm To Your Garden  Planting foam flowers will add whimsical charm to your springtime garden.

They typically bloom each year from June to October. The first to bloom are those at the flower's base. The flowers open and ascend the stems with pointy tips and coarsely serrated edges. They resemble candelabras (chandeliers) because of all the flower spikes that form on top. They grow up to five feet tall. Blue Vervain Adds Structure and Texture It features a bushy growth habit and dense foliage, making it ideal for adding structure to your yard. Its bushy appearance makes yards look fuller. The lance-shaped leaves come from their stems in alternating patterns, creating a textural contrast with other plants. The tiny, brightly colored blossoms enhance the aesthetic and architectural appeal of gardens and landscaping. Blue Vervain blooms boast a variety of colors, ranging from blue to deep purple to light lavender. On rare occasions, the flowers are white. The blooms have five joined petals at the base that create a small tube and are around 1/4 inch wide. A little stem supports the thin, lance-oblong leaves that grow up to seven inches long and one inch wide. These leaves have a pointy tip, coarsely serrated margins, and a broad base. The slightly hairy stems can be either green or reddish. Blue Vervain Has Purple & Blue Blooms They have bright blue-purple flowers containing a lot of nectar and pollen, which attract butterflies and other pollinators, such as bees and hummingbirds. Both the Verbena moth and the Common Buckeye butterfly lay their eggs on blue vervains. These plants usually attract the most pollinators during late summer and fall. Because few other plants bloom simultaneously, they attract many late-flying pollinators, which is good for the environment because it increases biodiversity.
