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
  • Silver sage (Salvia argentea) is a salvia perennial in USDA zones 5 to 8
  • 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.
