Blue plants and flowers can be hard to find in this corner of the world. When you travel, you may have noticed that in some tropical parts of the world, they have a lot of stunning blue plants. In this blog post, we’re going to share some of our favorite blue plants that are also very long-lasting and relatively easy to care for.

Salvias

Salvias are a nice clump-forming plant. They all have spiky flowers, and they range from a beautiful light blue to a dark purple. There’s even a pink one called Pink Profusion.

Some of the popular salvias include the following:

• Caradonna, which is a stunning bold color and has a really dark stem. It’s compact with a great shape to it.
• There is also the Blue by You (S. nemorosa x S. pratensis), which tends to bloom about two weeks earlier than the Caradonna.
• Then the Ostfriesland salvias that have been around for a long time, and landscapers still really love them. 

All of these stunning salvias are currently available at Blomidon Nurseries.

Russian Sage

The next one is Russian sage, also known as Perovskia. The leaves are sage green, it has this beautiful light purple flower and purple stem. The beautiful movement of this plant makes it look like ocean waves. With this plant, it’s important to know that it doesn’t like too much water. It is drought-tolerant, which makes it thrive in hot, dry, and sunny weather.

Phlox Divaricata (Blue Moon)

The Phlox divaricata, also known as Blue Moon, reaches about twelve to fourteen inches tall. This is a great woodland plant perfect for that shady spot in your garden. It can serve as a beautiful ground cover. In the center of the little four-petaled flower, you’ll see these little orange stamens that really stand out.

Agastache (Blue Fortune)

Agastache, or Blue Fortune, is a stunning plant with aromatic foliage. You can get this plant in oranges, corals, yellows, and reds. But this particular one, since we’re discussing blue flowers, is a light blue flower and a long bloomer, which is great to provide continuous color throughout the season.

Agastaches are a magnet for pollinators. It’s a butterfly-friendly plant that will attract hummingbirds and butterflies to your garden and contribute to local biodiversity.

Perennial Alliums

These are perennial alliums, not the bulbs you plant in the fall. These true perennials form beautiful clumps, producing perfect purple ball-shaped flowers on sturdy stems. They bloom in big clusters from late June to September. 

Many people think there’s a gap in flowering from July to August, but with the right perennials, your garden can stay in bloom all summer, which is what we want.

There’s no need for a lapse between spring and fall flowers—you can always have something in bloom.

Campanulas

Campanulas are beautiful, tall, bell-shaped flowers. There are a variety of Campanulas. The beautiful blue ones are called Takion or Takion Blue. They face upwards instead of down to the ground, which makes it easy to see them. They are about two-and-a-half feet tall and have a long blooming time as well. 

There’s also another one called Campanula Blue Waterfall. Instead of a very upright plant, this one will cascade down. 

Delphiniums

Delphiniums are tall, spiky, and very architectural-looking flowers. The blue one—the Blue Bird—is also called Candle Larkspur. It’s a spectacular-looking blue flower plant with a white-eyed center.

They come in whites, and there’s one called Black Knight, which is a really dark purple. Guinevere is mauve, and Galahad is white. The Round Table group!

Whether you are looking for more of a mix of colors or only the Blue Bird, you will love Delphiniums.

Lavender

Lavender is a wonderful, drought-tolerant plant. One thing about lavender is that you can trim it lightly, but not hard. They need to be high and dry and in a flower bed where the water would run away from them. With lavender, it’s important to allow the soil to dry out between watering sessions.
